[1/3] incubator-impala git commit: [DOCS] Genericize
RESERVATION_REQUEST_TIMEOUT page
Repository: incubator-impala
Updated Branches:
refs/heads/master 768383870 -> ff5d1ceb0
[DOCS] Genericize RESERVATION_REQUEST_TIMEOUT page
Since CDH 5 doesn't match up to a specific Impala version,
and this is an obsolete query option, just remove the
version reference rather than rewording it.

stray CDH references
Posted by jr...@apache.org.
IMPALA-3402: [DOCS] Remove more stray CDH references
A number of 'CDH' by itself were turned into substitution
variables resolving to 'Apache Hadoop'.
Also fixed some stray instances of CDH version numbers.
In some cases, 'CDH' or 'CDH 5' by itself was superfluous and was
just removed.

- Before installing Impala manually, make sure all applicable nodes have the appropriate hardware
- configuration, levels of operating system and CDH, and any other software prerequisites. See
- <xref href="impala_prereqs.xml#prereqs"/> for details.
- </p>
-
- <p>
- You can install Impala across many hosts or on one host:
- </p>
-
- <ul>
- <li>
- Installing Impala across multiple machines creates a distributed configuration. For best performance,
- install Impala on <b>all</b> DataNodes.
- </li>
-
- <li>
- Installing Impala on a single machine produces a pseudo-distributed cluster.
- </li>
- </ul>
-
- <p>
- <b>To install Impala on a host:</b>
- </p>
-
- <ol>
- <li>
- Install CDH as described in the Installation section of the
-<!-- Original URL: http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/latest/CDH5-Installation-Guide/CDH5-Installation-Guide.html -->
- <xref href="http://www.cloudera.com/documentation/enterprise/latest/topics/installation.html" scope="external" format="html">CDH
- 5 Installation Guide</xref>.
- </li>
-
- <li>
- <p>
- Install the Hive metastore somewhere in your cluster, as described in the Hive Installation topic in the
-<!-- Original URL: http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/latest/CDH5-Installation-Guide/cdh_ig_hive_installation.html -->
- <xref href="http://www.cloudera.com/documentation/enterprise/latest/topics/cdh_ig_hive_installation.html" scope="external" format="html">CDH
- 5 Installation Guide</xref>. As part of this process, you configure the Hive metastore to use an external
- database as a metastore. Impala uses this same database for its own table metadata. You can choose either
- a MySQL or PostgreSQL database as the metastore. The process for configuring each type of database is
- described in the CDH Installation Guide).
- </p>
- <p>
- Whenever practical, set up a Hive metastore service rather than connecting directly to the metastore
- database. Make sure the
- <filepath>/etc/impala/conf/hive-site.xml</filepath> file contains the following setting, substituting the
- appropriate hostname for <varname>metastore_server_host</varname>:
- </p>
-<codeblock><property>
-<name>hive.metastore.uris</name>
-<value>thrift://<varname>metastore_server_host</varname>:9083</value>
-</property>
-<property>
-<name>hive.metastore.client.socket.timeout</name>
-<value>3600</value>
-<description>MetaStore Client socket timeout in seconds</description>
-</property></codeblock>
- </li>
-
- <li>
- (Optional) If you installed the full Hive component on any host, you can verify that the metastore is
- configured properly by starting the Hive console and querying for the list of available tables. Once you
- confirm that the console starts, exit the console to continue the installation:
-<codeblock>$ hive
-Hive history file=/tmp/root/hive_job_log_root_201207272011_678722950.txt
-hive> show tables;
-table1
-table2
-hive> quit;
-$</codeblock>
- </li>
-
- <li>
- Confirm that your package management command is aware of the Impala repository settings, as described in
- <xref href="impala_prereqs.xml#prereqs"/>. You
- might need to download a repo or list file into a system directory underneath <filepath>/etc</filepath>.
- </li>
-
- <li>
- Use <b>one</b> of the following sets of commands to install the Impala package:
- <p>
- <b>For RHEL, Oracle Linux, or CentOS systems:</b>
- </p>
-<codeblock rev="1.2">$ sudo yum install impala # Binaries for daemons

-</codeblock>
- <note>
- <ph rev="upstream">Cloudera</ph> recommends that you not install Impala on any HDFS NameNode. Installing Impala on NameNodes
- provides no additional data locality, and executing queries with such a configuration might cause memory
- contention and negatively impact the HDFS NameNode.
- </note>
- </li>
-
- <li>
- Copy the client <codeph>hive-site.xml</codeph>, <codeph>core-site.xml</codeph>,
- <codeph>hdfs-site.xml</codeph>, and <codeph>hbase-site.xml</codeph> configuration files to the Impala
- configuration directory, which defaults to <codeph>/etc/impala/conf</codeph>. Create this directory if it
- does not already exist.

- <li>
- Use <b>one</b> of the following commands to install <codeph>impala-shell</codeph> on the machines from
- which you want to issue queries. You can install <codeph>impala-shell</codeph> on any supported machine
- that can connect to DataNodes that are running <codeph>impalad</codeph>.

-
- <li>
- Complete any required or recommended configuration, as described in
- <xref href="impala_config_performance.xml#config_performance"/>. Some of these configuration changes are
- mandatory.
- </li>

-
- <p>
- Once installation and configuration are complete, see <xref href="impala_processes.xml#processes"/> for how
- to activate the software on the appropriate nodes in your cluster.
