<div class="entry-content">
- <p>This summer I got the opportunity to intern with the Apache Kudu team at Cloudera.
-My project was to optimize the Kudu scan path by implementing a technique called
-index skip scan (a.k.a. scan-to-seek, see section 4.1 in [1]). I wanted to share
-my experience and the progress we’ve made so far on the approach.</p>
+ <p>Note: This is a cross-post from the Cloudera Engineering Blog
+<a href="https://blog.cloudera.com/blog/2019/04/fine-grained-authorization-with-apache-kudu-and-impala/">Fine-Grained Authorization with Apache Kudu and Impala</a></p>
+
+<p>Apache Impala supports fine-grained authorization via Apache Sentry on all of the tables it
+manages including Apache Kudu tables. Given Impala is a very common way to access the data stored
+in Kudu, this capability allows users deploying Impala and Kudu to fully secure the Kudu data in
+multi-tenant clusters even though Kudu does not yet have native fine-grained authorization of its
+own. This solution works because Kudu natively supports coarse-grained (all or nothing)
+authorization which enables blocking all access to Kudu directly except for the impala user and
+an optional whitelist of other trusted users. This post will describe how to use Apache Impala’s
+fine-grained authorization support along with Apache Kudu’s coarse-grained authorization to
+achieve a secure multi-tenant deployment.</p>
<!--more-->
-<p>Let’s begin with discussing the current query flow in Kudu.
-Consider the following table:</p>
-
-<div class="highlight"><pre><code class="language-sql" data-lang="sql"><span class="k">CREATE</span> <span class="k">TABLE</span> <span class="n">metrics</span> <span class="p">(</span>
- <span class="k">host</span> <span class="n">STRING</span><span class="p">,</span>
- <span class="n">tstamp</span> <span class="nb">INT</span><span class="p">,</span>
- <span class="n">clusterid</span> <span class="nb">INT</span><span class="p">,</span>
- <span class="k">role</span> <span class="n">STRING</span><span class="p">,</span>
- <span class="k">PRIMARY</span> <span class="k">KEY</span> <span class="p">(</span><span class="k">host</span><span class="p">,</span> <span class="n">tstamp</span><span class="p">,</span> <span class="n">clusterid</span><span class="p">)</span>
-<span class="p">);</span></code></pre></div>
-
-<p><img src="/img/index-skip-scan/example-table.png" alt="png" class="img-responsive" />
-<em>Sample rows of table <code>metrics</code> (sorted by key columns).</em></p>
-
-<p>In this case, by default, Kudu internally builds a primary key index (implemented as a
-<a href="https://en.wikipedia.org/wiki/B-tree">B-tree</a>) for the table <code>metrics</code>.
-As shown in the table above, the index data is sorted by the composite of all key columns.
-When the user query contains the first key column (<code>host</code>), Kudu uses the index (as the index data is
-primarily sorted on the first key column).</p>
-
-<p>Now, what if the user query does not contain the first key column and instead only contains the <code>tstamp</code> column?
-In the above case, the <code>tstamp</code> column values are sorted with respect to <code>host</code>,
-but are not globally sorted, and as such, it’s non-trivial to use the index to filter rows.
-Instead, a full tablet scan is done by default. Other databases may optimize such scans by building secondary indexes
-(though it might be redundant to build one on one of the primary keys). However, this isn’t an option for Kudu,
-given its lack of secondary index support.</p>
-
-<p>The question is, can Kudu do better than a full tablet scan here?</p>
-
-<p>The answer is yes! Let’s observe the column preceding the <code>tstamp</code> column. We will refer to it as the
-“prefix column” and its specific value as the “prefix key”. In this example, <code>host</code> is the prefix column.
-Note that the prefix keys are sorted in the index and that all rows of a given prefix key are also sorted by the
-remaining key columns. Therefore, we can use the index to skip to the rows that have distinct prefix keys,
-and also satisfy the predicate on the <code>tstamp</code> column.
-For example, consider the query:</p>

-<div class="highlight"><pre><code class="language-sql" data-lang="sql"><span class="k">SELECT</span> <span class="n">clusterid</span> <span class="k">FROM</span> <span class="n">metrics</span> <span class="k">WHERE</span> <span class="n">tstamp</span> <span class="o">=</span> <span class="mi">100</span><span class="p">;</span></code></pre></div>

-<p><img src="/img/index-skip-scan/skip-scan-example-table.png" alt="png" class="img-responsive" />
-<em>Skip scan flow illustration. The rows in green are scanned and the rest are skipped.</em></p>
-
-<p>The tablet server can use the index to <strong>skip</strong> to the first row with a distinct prefix key (<code>host = helium</code>) that
-matches the predicate (<code>tstamp = 100</code>) and then <strong>scan</strong> through the rows until the predicate no longer matches. At that
-point we would know that no more rows with <code>host = helium</code> will satisfy the predicate, and we can skip to the next
-prefix key. This holds true for all distinct keys of <code>host</code>. Hence, this method is popularly known as
-<strong>skip scan optimization</strong>[2, 3].</p>
-
-<h1 id="performance">Performance</h1>
-
-<p>This optimization can speed up queries significantly, depending on the cardinality (number of distinct values) of the
-prefix column. The lower the prefix column cardinality, the better the skip scan performance. In fact, when the
-prefix column cardinality is high, skip scan is not a viable approach. The performance graph (obtained using the example
-schema and query pattern mentioned earlier) is shown below.</p>
-
-<p>Based on our experiments, on up to 10 million rows per tablet (as shown below), we found that the skip scan performance
-begins to get worse with respect to the full tablet scan performance when the prefix column cardinality
-exceeds sqrt(number_of_rows_in_tablet).
-Therefore, in order to use skip scan performance benefits when possible and maintain a consistent performance in cases
-of large prefix column cardinality, we have tentatively chosen to dynamically disable skip scan when the number of skips for
-distinct prefix keys exceeds sqrt(number_of_rows_in_tablet).
-It will be an interesting project to further explore sophisticated heuristics to decide when
-to dynamically disable skip scan.</p>
-

-
-<h1 id="conclusion">Conclusion</h1>
-
-<p>Skip scan optimization in Kudu can lead to huge performance benefits that scale with the size of
-data in Kudu tablets. This is a work-in-progress <a href="https://gerrit.cloudera.org/#/c/10983/">patch</a>.
-The implementation in the patch works only for equality predicates on the non-first primary key
-columns. An important point to note is that although, in the above specific example, the number of prefix
-columns is one (<code>host</code>), this approach is generalized to work with any number of prefix columns.</p>
-
-<p>This work also lays the groundwork to leverage the skip scan approach and optimize query processing time in the
-following use cases:</p>
+<h2 id="sample-workflow">Sample Workflow</h2>
-<ul>
- <li>Range predicates</li>
- <li>In-list predicates</li>
-</ul>
+<p>The examples in this post enable a workflow that uses Apache Spark to ingest data directly into
+Kudu and Impala to run analytic queries on that data. The Spark job, run as the <code>etl_service</code> user,
+is permitted to access the Kudu data via coarse-grained authorization. Even though this gives
+access to all the data in Kudu, the <code>etl_service</code> user is only used for scheduled jobs or by an
+administrator. All queries on the data, from a wide array of users, will use Impala and leverage
+Impala’s fine-grained authorization. Impala’s
+<a href="https://impala.apache.org/docs/build/html/topics/impala_grant.html"><code>GRANT</code> statements</a>
+allow you to flexibly control the privileges on the Kudu storage tables. Impala’s fine-grained
+privileges along with support for
+<a href="https://impala.apache.org/docs/build/html/topics/impala_select.html"><code>SELECT</code></a>,
+<a href="https://impala.apache.org/docs/build/html/topics/impala_insert.html"><code>INSERT</code></a>,
+<a href="https://impala.apache.org/docs/build/html/topics/impala_update.html"><code>UPDATE</code></a>,
+<a href="https://impala.apache.org/docs/build/html/topics/impala_upsert.html"><code>UPSERT</code></a>,
+and <a href="https://impala.apache.org/docs/build/html/topics/impala_delete.html"><code>DELETE</code></a>
+statements, allow you to finely control who can read and write data to your Kudu tables while
+using Impala. Below is a diagram showing the workflow described:</p>
-<p>This was my first time working on an open source project. I thoroughly enjoyed working on this challenging problem,
-right from understanding the scan path in Kudu to working on a full-fledged implementation of
-the skip scan optimization. I am very grateful to the Kudu team for guiding and supporting me throughout the
-internship period.</p>

+<p>Kudu supports coarse-grained authorization of client requests based on the authenticated client
+Kerberos principal. The two levels of access which can be configured are:</p>
-<p><a href="https://www.sqlite.org/optoverview.html#skipscan">[3]</a>: Skip Scan - SQLite</p>
+<ul>
+ <li><em>Superuser</em> – principals authorized as a superuser are able to perform certain administrative
+functionality such as using the kudu command line tool to diagnose or repair cluster issues.</li>
+ <li><em>User</em> – principals authorized as a user are able to access and modify all data in the Kudu
+cluster. This includes the ability to create, drop, and alter tables as well as read, insert,
+update, and delete data.</li>
+</ul>
+<p>Access levels are granted using whitelist-style Access Control Lists (ACLs), one for each of the
+two levels. Each access control list either specifies a comma-separated list of users, or may be
+set to <code>*</code> to indicate that all authenticated users are able to gain access at the specified level.</p>
+
+<p><em>Note</em>: The default value for the User ACL is <code>*</code>, which allows all users access to the cluster.</p>
+
+<h3 id="example-configuration">Example Configuration</h3>
+
+<p>The first and most important step is to remove the default ACL of <code>*</code> from Kudu’s
+<a href="https://kudu.apache.org/docs/configuration_reference.html#kudu-master_user_acl"><code>–user_acl</code> configuration</a>.
+This will ensure only the users you list will have access to the Kudu cluster. Then, to allow the
+Impala service to access all of the data in Kudu, the Impala service user, usually impala, should
+be added to the Kudu <code>–user_acl</code> configuration. Any user that is not using Impala will also need
+to be added to this list. For example, an Apache Spark job might be used to load data directly
+into Kudu. Generally, a single user is used to run scheduled jobs of applications that do not
+support fine-grained authorization on their own. For this example, that user is <code>etl_service</code>. The
+full <code>–user_acl</code> configuration is:</p>
+
+<div class="highlight"><pre><code class="language-bash" data-lang="bash">--user_acl<span class="o">=</span>impala,etl_service</code></pre></div>
+
+<p>For more details see the Kudu
+<a href="https://kudu.apache.org/docs/security.html#_coarse_grained_authorization">authorization documentation</a>.</p>
+
+<h2 id="using-impalas-fine-grained-authorization">Using Impala’s Fine-Grained Authorization</h2>
+
+<p>Follow Impala’s
+<a href="https://impala.apache.org/docs/build/html/topics/impala_authorization.html">authorization documentation</a>
+to configure fine-grained authorization. Once configured, you can use Impala’s
+<a href="https://impala.apache.org/docs/build/html/topics/impala_grant.html"><code>GRANT</code> statements</a>
+to control the privileges of Kudu tables. These fine-grained privileges can be set at the database,
+table and column level. Additionally you can individually control <code>SELECT</code>, <code>INSERT</code>, <code>CREATE</code>,
+<code>ALTER</code>, and <code>DROP</code> privileges.</p>
+
+<p><em>Note</em>: A user needs the <code>ALL</code> privilege in order to run <code>DELETE</code>, <code>UPDATE</code>, or <code>UPSERT</code>
+statements against a Kudu table.</p>
+
+<p>Below is a brief example with a couple tables stored in Kudu:</p>
+
+<div class="highlight"><pre><code class="language-sql" data-lang="sql"><span class="k">CREATE</span> <span class="k">TABLE</span> <span class="n">messages</span>

+
+<h2 id="conclusion">Conclusion</h2>
+
+<p>This brief example that combines Kudu’s coarse-grained authorization and Impala’s fine-grained
+authorization should enable you to meet the security needs of your data workflow today. The
+pattern described here can be applied to other services and workflows using Kudu as well. For
+greater authorization flexibility, you can look forward to the near future when Kudu supports
+native fine-grained authorization on its own. The Apache Kudu contributors understand the
+importance of native fine-grained authorization and they are working on integrations with
+Apache Sentry and Apache Ranger.</p>

+
+<p>Apache Impala supports fine-grained authorization via Apache Sentry on all of the tables it
+manages including Apache Kudu tables. Given Impala is a very common way to access the data stored
+in Kudu, this capability allows users deploying Impala and Kudu to fully secure the Kudu data in
+multi-tenant clusters even though Kudu does not yet have native fine-grained authorization of its
+own. This solution works because Kudu natively supports coarse-grained (all or nothing)
+authorization which enables blocking all access to Kudu directly except for the impala user and
+an optional whitelist of other trusted users. This post will describe how to use Apache Impala’s
+fine-grained authorization support along with Apache Kudu’s coarse-grained authorization to
+achieve a secure multi-tenant deployment.</p>

+
+<p>Apache Impala supports fine-grained authorization via Apache Sentry on all of the tables it
+manages including Apache Kudu tables. Given Impala is a very common way to access the data stored
+in Kudu, this capability allows users deploying Impala and Kudu to fully secure the Kudu data in
+multi-tenant clusters even though Kudu does not yet have native fine-grained authorization of its
+own. This solution works because Kudu natively supports coarse-grained (all or nothing)
+authorization which enables blocking all access to Kudu directly except for the impala user and
+an optional whitelist of other trusted users. This post will describe how to use Apache Impala’s
+fine-grained authorization support along with Apache Kudu’s coarse-grained authorization to
+achieve a secure multi-tenant deployment.</p>
+
+<!--more-->
+
+<h2 id="sample-workflow">Sample Workflow</h2>
+
+<p>The examples in this post enable a workflow that uses Apache Spark to ingest data directly into
+Kudu and Impala to run analytic queries on that data. The Spark job, run as the <code>etl_service</code> user,
+is permitted to access the Kudu data via coarse-grained authorization. Even though this gives
+access to all the data in Kudu, the <code>etl_service</code> user is only used for scheduled jobs or by an
+administrator. All queries on the data, from a wide array of users, will use Impala and leverage
+Impala’s fine-grained authorization. Impala’s
+<a href="https://impala.apache.org/docs/build/html/topics/impala_grant.html"><code>GRANT</code> statements</a>
+allow you to flexibly control the privileges on the Kudu storage tables. Impala’s fine-grained
+privileges along with support for
+<a href="https://impala.apache.org/docs/build/html/topics/impala_select.html"><code>SELECT</code></a>,
+<a href="https://impala.apache.org/docs/build/html/topics/impala_insert.html"><code>INSERT</code></a>,
+<a href="https://impala.apache.org/docs/build/html/topics/impala_update.html"><code>UPDATE</code></a>,
+<a href="https://impala.apache.org/docs/build/html/topics/impala_upsert.html"><code>UPSERT</code></a>,
+and <a href="https://impala.apache.org/docs/build/html/topics/impala_delete.html"><code>DELETE</code></a>
+statements, allow you to finely control who can read and write data to your Kudu tables while
+using Impala. Below is a diagram showing the workflow described:</p>
+
+<p><img src="/img/fine-grained-authorization-with-apache-kudu.png" alt="png" class="img-responsive" /></p>
+
+<p><em>Note</em>: The examples below assume that Authorization has already been configured for Kudu, Impala,
+and Spark. For help configuring authorization see the Cloudera
+<a href="https://www.cloudera.com/documentation/enterprise/latest/topics/sg_auth_overview.html">authorization documentation</a>.</p>
+
+<h2 id="configuring-kudus-coarse-grained-authorization">Configuring Kudu’s Coarse-Grained Authorization</h2>
+
+<p>Kudu supports coarse-grained authorization of client requests based on the authenticated client
+Kerberos principal. The two levels of access which can be configured are:</p>
+
+<ul>
+ <li><em>Superuser</em> – principals authorized as a superuser are able to perform certain administrative
+functionality such as using the kudu command line tool to diagnose or repair cluster issues.</li>
+ <li><em>User</em> – principals authorized as a user are able to access and modify all data in the Kudu
+cluster. This includes the ability to create, drop, and alter tables as well as read, insert,
+update, and delete data.</li>
+</ul>
+
+<p>Access levels are granted using whitelist-style Access Control Lists (ACLs), one for each of the
+two levels. Each access control list either specifies a comma-separated list of users, or may be
+set to <code>*</code> to indicate that all authenticated users are able to gain access at the specified level.</p>
+
+<p><em>Note</em>: The default value for the User ACL is <code>*</code>, which allows all users access to the cluster.</p>
+
+<h3 id="example-configuration">Example Configuration</h3>
+
+<p>The first and most important step is to remove the default ACL of <code>*</code> from Kudu’s
+<a href="https://kudu.apache.org/docs/configuration_reference.html#kudu-master_user_acl"><code>–user_acl</code> configuration</a>.
+This will ensure only the users you list will have access to the Kudu cluster. Then, to allow the
+Impala service to access all of the data in Kudu, the Impala service user, usually impala, should
+be added to the Kudu <code>–user_acl</code> configuration. Any user that is not using Impala will also need
+to be added to this list. For example, an Apache Spark job might be used to load data directly
+into Kudu. Generally, a single user is used to run scheduled jobs of applications that do not
+support fine-grained authorization on their own. For this example, that user is <code>etl_service</code>. The
+full <code>–user_acl</code> configuration is:</p>
+
+<div class="highlight"><pre><code class="language-bash" data-lang="bash">--user_acl<span class="o">=</span>impala,etl_service</code></pre></div>
+
+<p>For more details see the Kudu
+<a href="https://kudu.apache.org/docs/security.html#_coarse_grained_authorization">authorization documentation</a>.</p>
+
+<h2 id="using-impalas-fine-grained-authorization">Using Impala’s Fine-Grained Authorization</h2>
+
+<p>Follow Impala’s
+<a href="https://impala.apache.org/docs/build/html/topics/impala_authorization.html">authorization documentation</a>
+to configure fine-grained authorization. Once configured, you can use Impala’s
+<a href="https://impala.apache.org/docs/build/html/topics/impala_grant.html"><code>GRANT</code> statements</a>
+to control the privileges of Kudu tables. These fine-grained privileges can be set at the database,
+table and column level. Additionally you can individually control <code>SELECT</code>, <code>INSERT</code>, <code>CREATE</code>,
+<code>ALTER</code>, and <code>DROP</code> privileges.</p>
+
+<p><em>Note</em>: A user needs the <code>ALL</code> privilege in order to run <code>DELETE</code>, <code>UPDATE</code>, or <code>UPSERT</code>
+statements against a Kudu table.</p>
+
+<p>Below is a brief example with a couple tables stored in Kudu:</p>
+

+
+<h2 id="conclusion">Conclusion</h2>
+
+<p>This brief example that combines Kudu’s coarse-grained authorization and Impala’s fine-grained
+authorization should enable you to meet the security needs of your data workflow today. The
+pattern described here can be applied to other services and workflows using Kudu as well. For
+greater authorization flexibility, you can look forward to the near future when Kudu supports
+native fine-grained authorization on its own. The Apache Kudu contributors understand the
+importance of native fine-grained authorization and they are working on integrations with
+Apache Sentry and Apache Ranger.</p></content><author><name>Grant Henke</name></author><summary>Note: This is a cross-post from the Cloudera Engineering Blog

+in Kudu, this capability allows users deploying Impala and Kudu to fully secure the Kudu data in
+multi-tenant clusters even though Kudu does not yet have native fine-grained authorization of its
+own. This solution works because Kudu natively supports coarse-grained (all or nothing)
+authorization which enables blocking all access to Kudu directly except for the impala user and
+an optional whitelist of other trusted users. This post will describe how to use Apache Impala’s
+fine-grained authorization support along with Apache Kudu’s coarse-grained authorization to
+achieve a secure multi-tenant deployment.</summary></entry><entry><title>Testing Apache Kudu Applications on the JVM</title><link href="/2019/03/19/testing-apache-kudu-applications-on-the-jvm.html" rel="alternate" type="text/html" title="Testing Apache Kudu Applications on the JVM" /><published>2019-03-19T00:00:00-05:00</published><updated>2019-03-19T00:00:00-05:00</updated><id>/2019/03/19/testing-apache-kudu-applications-on-the-jvm</id><content type="html" xml:base="/2019/03/19/testing- [...]

-<p>Apache Kudu 1.7.0 is a minor release that offers new features, performance
-optimizations, incremental improvements, and bug fixes.</p>
-
-<p>Release highlights:</p>
-
-<!--more-->
-
-<ol>
- <li>Kudu now supports the decimal column type. The decimal type is a numeric
-data type with fixed scale and precision suitable for financial and other
-arithmetic calculations where the imprecise representation and rounding
-behavior of float and double make those types impractical. The decimal type
-is also useful for integers larger than int64 and cases with fractional values
-in a primary key. See <a href="/releases/1.7.0/docs/schema_design.html#decimal">Decimal Type</a>
-for more details.</li>
- <li>The strategy Kudu uses for automatically healing tablets which have lost a
-replica due to server or disk failures has been improved. The new re-replication
-strategy, or replica management scheme, first adds a replacement tablet replica
-before evicting the failed one.</li>
- <li>A new scan read mode READ_YOUR_WRITES. Users can specify READ_YOUR_WRITES when
-creating a new scanner in C++, Java and Python clients. If this mode is used,
-the client will perform a read such that it follows all previously known writes
-and reads from this client. Reads in this mode ensure read-your-writes and
-read-your-reads session guarantees, while minimizing latency caused by waiting
-for outstanding write transactions to complete. Note that this is still an
-experimental feature which may be stabilized in future releases.</li>
- <li>The tablet server web UI scans dashboard (/scans) has been improved with several
-new features, including: showing the most recently completed scans, a pseudo-SQL
-scan descriptor that concisely shows the selected columns and applied predicates,
-and more complete and better documented scan statistics.</li>
- <li>Kudu daemons now expose a web page /stacks which dumps the current stack trace of
-every thread running in the server. This information can be helpful when diagnosing
-performance issues.</li>
- <li>By default, each tablet replica will now stripe data blocks across 3 data directories
-instead of all data directories. This decreases the likelihood that any given tablet
-will be affected in the event of a single disk failure.</li>
- <li>The Java client now uses a predefined prioritized list of TLS ciphers when
-establishing an encrypted connection to Kudu servers. This cipher list matches the
-list of ciphers preferred for server-to-server communication and ensures that the
-most efficient and secure ciphers are preferred. When the Kudu client is running on
-Java 8 or newer, this provides a substantial speed-up to read and write performance.</li>
- <li>The performance of inserting rows containing many string or binary columns has been
-improved, especially in the case of highly concurrent write workloads.</li>
- <li>The Java client will now automatically attempt to re-acquire Kerberos credentials
-from the ticket cache when the prior credentials are about to expire. This allows
-client instances to persist longer than the expiration time of a single Kerberos
-ticket so long as some other process renews the credentials in the ticket cache.</li>
