+* [MAPREDUCE-7069](https://issues.apache.org/jira/browse/MAPREDUCE-7069) | *Major* | **Add ability to specify user environment variables individually**
+
+Environment variables for MapReduce tasks can now be specified as separate properties, e.g.:
+mapreduce.map.env.VARNAME=value
+mapreduce.reduce.env.VARNAME=value
+yarn.app.mapreduce.am.env.VARNAME=value
+yarn.app.mapreduce.am.admin.user.env.VARNAME=value
+This form of specifying environment variables is useful when the value of an environment variable contains commas.
+
+

+
+* [HDFS-15281](https://issues.apache.org/jira/browse/HDFS-15281) | *Major* | **ZKFC ignores dfs.namenode.rpc-bind-host and uses dfs.namenode.rpc-address to bind to host address**
+
+ZKFC binds host address to "dfs.namenode.servicerpc-bind-host", if configured. Otherwise, it binds to "dfs.namenode.rpc-bind-host". If neither of those is configured, ZKFC binds itself to NameNode RPC server address (effectively "dfs.namenode.rpc-address").

+---
+
+* [HADOOP-17089](https://issues.apache.org/jira/browse/HADOOP-17089) | *Critical* | **WASB: Update azure-storage-java SDK**
+
+Azure WASB bug fix that can cause list results to appear empty.
+
+
+---
+
+* [YARN-7677](https://issues.apache.org/jira/browse/YARN-7677) | *Major* | **Docker image cannot set HADOOP\_CONF\_DIR**
+
+The HADOOP\_CONF\_DIR environment variable is no longer unconditionally inherited by containers even if it does not appear in the nodemanager whitelist variables specified by the yarn.nodemanager.env-whitelist property. If the whitelist property has been modified from the default to not include HADOOP\_CONF\_DIR yet containers need it to be inherited from the nodemanager's environment then the whitelist settings need to be updated to include HADOOP\_CONF\_DIR.

+# Apache Hadoop 3.1.4 Release Notes
+
+These release notes cover new developer and user-facing incompatibilities, important issues, features, and major improvements.

+
+* [HDFS-13806](https://issues.apache.org/jira/browse/HDFS-13806) | *Minor* | **EC: No error message for unsetting EC policy of the directory inherits the erasure coding policy from an ancestor directory**
+
+After this change, attempt to unsetErasureCodingPolicy() on a directory without EC policy explicitly set on it, will get NoECPolicySetException.

+
+* [HDFS-14890](https://issues.apache.org/jira/browse/HDFS-14890) | *Blocker* | **Setting permissions on name directory fails on non posix compliant filesystems**
+
+- Fixed namenode/journal startup on Windows.

+---
+
+* [HDFS-14745](https://issues.apache.org/jira/browse/HDFS-14745) | *Major* | **Backport HDFS persistent memory read cache support to branch-3.1**
+
+Non-volatile storage class memory (SCM, also known as persistent memory) is supported in HDFS cache. To enable SCM cache, user just needs to configure SCM volume for property “dfs.datanode.cache.pmem.dirs” in hdfs-site.xml. And all HDFS cache directives keep unchanged. There are two implementations for HDFS SCM Cache, one is pure java code implementation and the other is native PMDK based implementation. The latter implementation can bring user better performance gain in cache write and [...]

+
+* [HDFS-12943](https://issues.apache.org/jira/browse/HDFS-12943) | *Major* | **Consistent Reads from Standby Node**
+
+Observer is a new type of a NameNode in addition to Active and Standby Nodes in HA settings. An Observer Node maintains a replica of the namespace same as a Standby Node. It additionally allows execution of clients read requests.
+
+To ensure read-after-write consistency within a single client, a state ID is introduced in RPC headers. The Observer responds to the client request only after its own state has caught up with the client’s state ID, which it previously received from the Active NameNode.
+
+Clients can explicitly invoke a new client protocol call msync(), which ensures that subsequent reads by this client from an Observer are consistent.
+
+A new client-side ObserverReadProxyProvider is introduced to provide automatic switching between Active and Observer NameNodes for submitting respectively write and read requests.
+
+
+---
+
+* [HADOOP-16771](https://issues.apache.org/jira/browse/HADOOP-16771) | *Major* | **Update checkstyle to 8.26 and maven-checkstyle-plugin to 3.1.0**
+
+Updated checkstyle to 8.26 and updated maven-checkstyle-plugin to 3.1.0.
+
+
+---
+
+* [HDFS-15281](https://issues.apache.org/jira/browse/HDFS-15281) | *Major* | **ZKFC ignores dfs.namenode.rpc-bind-host and uses dfs.namenode.rpc-address to bind to host address**
+
+ZKFC binds host address to "dfs.namenode.servicerpc-bind-host", if configured. Otherwise, it binds to "dfs.namenode.rpc-bind-host". If neither of those is configured, ZKFC binds itself to NameNode RPC server address (effectively "dfs.namenode.rpc-address").

+
+In progress upgrade status may show READY state sooner than actual upgrade operations. External caller to upgrade API is recommended to wait minimum 30 seconds before querying yarn app -status.
+
+

+
+* [HADOOP-15996](https://issues.apache.org/jira/browse/HADOOP-15996) | *Major* | **Plugin interface to support more complex usernames in Hadoop**
+
+This patch enables "Hadoop" and "MIT" as options for "hadoop.security.auth\_to\_local.mechanism" and defaults to 'hadoop'. This should be backward compatible with pre-HADOOP-12751.
+
+This is basically HADOOP-12751 plus configurable + extended tests.

+
+After this change, capacity scheduler queue is able to inherit and override max-allocation from its parent queue. The subqueue's max-allocation can be larger or smaller than the parent queue's but can't exceed the global "yarn.scheduler.capacity.maximum-allocation". User can set queue-level max-allocation on any level of queues, using configuration property "yarn.scheduler.capacity.%QUEUE\_PATH%.maximum-allocation". And this property allows user to set max-resource-allocation for customi [...]

+
+---
+
+* [HADOOP-16011](https://issues.apache.org/jira/browse/HADOOP-16011) | *Major* | **OsSecureRandom very slow compared to other SecureRandom implementations**
+
+The default RNG is now OpensslSecureRandom instead of OsSecureRandom.The high-performance hardware random number generator (RDRAND instruction) will be used if available. If not, it will fall back to OpenSSL secure random generator.
+If you insist on using OsSecureRandom, set hadoop.security.secure.random.impl in core-site.xml to org.apache.hadoop.crypto.random.OsSecureRandom.
+
+
+---
+
+* [HADOOP-16210](https://issues.apache.org/jira/browse/HADOOP-16210) | *Critical* | **Update guava to 27.0-jre in hadoop-project trunk**
+
+Guava has been updated to 27.0. Code built against this new version may not link against older releases because of new overloads of methods like Preconditions.checkArgument().
+
+
+---
+
+* [HADOOP-16085](https://issues.apache.org/jira/browse/HADOOP-16085) | *Major* | **S3Guard: use object version or etags to protect against inconsistent read after replace/overwrite**
+
+S3Guard will now track the etag of uploaded files and, if an S3 bucket is versioned, the object version. You can then control how to react to a mismatch between the data in the DynamoDB table and that in the store: warn, fail, or, when using versions, return the original value.
+
+This adds two new columns to the table: etag and version. This is transparent to older S3A clients -but when such clients add/update data to the S3Guard table, they will not add these values. As a result, the etag/version checks will not work with files uploaded by older clients.
+
+For a consistent experience, upgrade all clients to use the latest hadoop version.
+
+
+---
+
+* [HADOOP-15563](https://issues.apache.org/jira/browse/HADOOP-15563) | *Major* | **S3Guard to support creating on-demand DDB tables**
+
+S3Guard now defaults to creating DynamoDB tables as "On-Demand", rather than with a prepaid IO capacity. This reduces costs when idle to only the storage of the metadata entries, while delivering significantly faster performance during query planning and other bursts of IO. Consult the S3Guard documentation for further details.
+
+
+---
+
+* [YARN-9578](https://issues.apache.org/jira/browse/YARN-9578) | *Major* | **Add limit/actions/summarize options for app activities REST API**
+
+This patch changes the format of app activities query URL to http://{rm-host}:{port}/ws/v1/cluster/scheduler/app-activities/{app-id}/, app-id now is a path parameter instead of a query parameter.
+
+
+---
+
+* [HDFS-14339](https://issues.apache.org/jira/browse/HDFS-14339) | *Major* | **Inconsistent log level practices in RpcProgramNfs3.java**
+
+**WARNING: No release note provided for this change.**
+
+
+---
+
+* [HDFS-14403](https://issues.apache.org/jira/browse/HDFS-14403) | *Major* | **Cost-Based RPC FairCallQueue**
+
+This adds an extension to the IPC FairCallQueue which allows for the consideration of the \*cost\* of a user's operations when deciding how they should be prioritized, as opposed to the number of operations. This can be helpful for protecting the NameNode from clients which submit very expensive operations (e.g. large listStatus operations or recursive getContentSummary operations).
+
+This can be enabled by setting the \`ipc.\<port\>.costprovder.impl\` configuration to \`org.apache.hadoop.ipc.WeightedTimeCostProvider\`.
+
+
+---
+
+* [HADOOP-16460](https://issues.apache.org/jira/browse/HADOOP-16460) | *Major* | **ABFS: fix for Sever Name Indication (SNI)**
+
+ABFS: Bug fix to support Server Name Indication (SNI).
+
+
+---
+
+* [HADOOP-16452](https://issues.apache.org/jira/browse/HADOOP-16452) | *Major* | **Increase ipc.maximum.data.length default from 64MB to 128MB**
+
+Default ipc.maximum.data.length is now 128 MB in order to accommodate huge block reports.
+
+
+---
+
+* [HDFS-13783](https://issues.apache.org/jira/browse/HDFS-13783) | *Major* | **Balancer: make balancer to be a long service process for easy to monitor it.**
+
+Adds a new parameter to the Balancer CLI, "-asService", to enable the process to be long-running.
+
+
+---
+
+* [HADOOP-16398](https://issues.apache.org/jira/browse/HADOOP-16398) | *Major* | **Exports Hadoop metrics to Prometheus**
+
+If "hadoop.prometheus.endpoint.enabled" is set to true, Prometheus-friendly formatted metrics can be obtained from '/prom' endpoint of Hadoop daemons. The default value of the property is false.
+
+
+---
+
+* [HADOOP-16479](https://issues.apache.org/jira/browse/HADOOP-16479) | *Major* | **ABFS FileStatus.getModificationTime returns localized time instead of UTC**
+
+private long parseLastModifiedTime(final String lastModifiedTime)
+
+Timezone is part of lastModifiedTime String as it's last field. But when parsed it ignores timezone field and assumes JVM timezone.
+Fix: Made timezone field considered in lastModifiedTime when the same is parsed
+
+
+---
+
+* [HADOOP-16499](https://issues.apache.org/jira/browse/HADOOP-16499) | *Critical* | **S3A retry policy to be exponential**
+
+The S3A filesystem now backs off exponentially on failures. if you have customized the fs.s3a.retry.limit and fs.s3a.retry.interval options you may wish to review these settings
+
+
+---
+
+* [HDFS-13505](https://issues.apache.org/jira/browse/HDFS-13505) | *Major* | **Turn on HDFS ACLs by default.**
+
+By default, dfs.namenode.acls.enabled is now set to true. If you haven't set dfs.namenode.acls.enabled=false before and want to keep ACLs feature disabled, you must explicitly set it to false in hdfs-site.xml. i.e.
+ \<property\>
+ \<name\>dfs.namenode.acls.enabled\</name\>
+ \<value\>false\</value\>
+ \</property\>
+
+
+---
+
+* [YARN-2599](https://issues.apache.org/jira/browse/YARN-2599) | *Major* | **Standby RM should expose jmx endpoint**
+
+YARN /jmx URL end points will be accessible per resource manager process. Hence there will not be any redirection to active resource manager while accessing /jmx endpoints.
+
+
+---
+
+* [HDFS-13101](https://issues.apache.org/jira/browse/HDFS-13101) | *Critical* | **Yet another fsimage corruption related to snapshot**
+
+Fix a corner case in deleting HDFS snapshots. A regression was later found and fixed by HDFS-15012.
+
+
+---
+
+* [HDFS-14675](https://issues.apache.org/jira/browse/HDFS-14675) | *Major* | **Increase Balancer Defaults Further**
+
+Increase default bandwidth limit for rebalancing per DataNode (dfs.datanode.balance.bandwidthPerSec) from 10MB/s to 100MB/s.
+
+Increase default maximum threads of DataNode balancer (dfs.datanode.balance.max.concurrent.moves) from 50 to 100.
+
+
+---
+
+* [HDFS-14617](https://issues.apache.org/jira/browse/HDFS-14617) | *Major* | **Improve fsimage load time by writing sub-sections to the fsimage index**
+
+This change allows the inode and inode directory sections of the fsimage to be loaded in parallel. Tests on large images have shown this change to reduce the image load time to about 50% of the pre-change run time.
+
+It works by writing sub-section entries to the image index, effectively splitting each image section into many sub-sections which can be processed in parallel. By default 12 sub-sections per image section are created when the image is saved, and 4 threads are used to load the image at startup.
+
+This is disabled by default for any image with more than 1M inodes (dfs.image.parallel.inode.threshold) and can be enabled by setting dfs.image.parallel.load to true. When the feature is enabled, the next HDFS checkpoint will write the image sub-sections and subsequent namenode restarts can load the image in parallel.
+
+A image with the parallel sections can be read even if the feature is disabled, but HDFS versions without this Jira cannot load an image with parallel sections. OIV can process a parallel enabled image without issues.
+
+Key configuration parameters are:
+
+dfs.image.parallel.load=false - enable or disable the feature
+
+dfs.image.parallel.target.sections = 12 - The target number of subsections. Aim for 2 to 3 times the number of dfs.image.parallel.threads.
+
+dfs.image.parallel.inode.threshold = 1000000 - Only save and load in parallel if the image has more than this number of inodes.
+
+dfs.image.parallel.threads = 4 - The number of threads used to load the image. Testing has shown 4 to be optimal, but this may depends on the environment
+
+
+---
+
+* [HDFS-14396](https://issues.apache.org/jira/browse/HDFS-14396) | *Blocker* | **Failed to load image from FSImageFile when downgrade from 3.x to 2.x**
+
+During a rolling upgrade from Hadoop 2.x to 3.x, NameNode cannot persist erasure coding information, and therefore a user cannot start using erasure coding feature until finalize is done.
+
+
+---
+
+* [HADOOP-16554](https://issues.apache.org/jira/browse/HADOOP-16554) | *Major* | **mvn javadoc:javadoc fails in hadoop-aws**
+
+Fixed the link for javadoc of hadoop-aws CommitOperations
+
+
+---
+
+* [HADOOP-16557](https://issues.apache.org/jira/browse/HADOOP-16557) | *Major* | **[pb-upgrade] Upgrade protobuf.version to 3.7.1**
+
+Upgraded the protobuf to 3.7.1.
+
+
+---
+
+* [HDFS-14845](https://issues.apache.org/jira/browse/HDFS-14845) | *Critical* | **Ignore AuthenticationFilterInitializer for HttpFSServerWebServer and honor hadoop.http.authentication configs**
+
+httpfs.authentication.\* configs become deprecated and hadoop.http.authentication.\* configs are honored in HttpFS. If the both configs are set, httpfs.authentication.\* configs are effective for compatibility.
+
+
+---
+
+* [HADOOP-15616](https://issues.apache.org/jira/browse/HADOOP-15616) | *Major* | **Incorporate Tencent Cloud COS File System Implementation**
+
+Tencent cloud is top 2 cloud vendors in China market and the object store COS is widely used among China’s cloud users. This task implements a COSN filesytem to support Tencent cloud COS natively in Hadoop. With simple configuration, Hadoop applications, like Spark and Hive, can read/write data from COS without any code change.
+
+
+---
+
+* [HDFS-13762](https://issues.apache.org/jira/browse/HDFS-13762) | *Major* | **Support non-volatile storage class memory(SCM) in HDFS cache directives**
+
+Non-volatile storage class memory (SCM, also known as persistent memory) is supported in HDFS cache. To enable SCM cache, user just needs to configure SCM volume for property “dfs.datanode.cache.pmem.dirs” in hdfs-site.xml. And all HDFS cache directives keep unchanged. There are two implementations for HDFS SCM Cache, one is pure java code implementation and the other is native PMDK based implementation. The latter implementation can bring user better performance gain in cache write and [...]

+
+* [HDFS-14890](https://issues.apache.org/jira/browse/HDFS-14890) | *Blocker* | **Setting permissions on name directory fails on non posix compliant filesystems**
+
+- Fixed namenode/journal startup on Windows.
+
+
+---
+
+* [HADOOP-16152](https://issues.apache.org/jira/browse/HADOOP-16152) | *Major* | **Upgrade Eclipse Jetty version to 9.4.x**
+
+Upgraded Jetty to 9.4.20.v20190813.
+Downstream applications that still depend on Jetty 9.3.x may break.
+
+
+---
+
+* [HDFS-12943](https://issues.apache.org/jira/browse/HDFS-12943) | *Major* | **Consistent Reads from Standby Node**
+
+Observer is a new type of a NameNode in addition to Active and Standby Nodes in HA settings. An Observer Node maintains a replica of the namespace same as a Standby Node. It additionally allows execution of clients read requests.
+
+To ensure read-after-write consistency within a single client, a state ID is introduced in RPC headers. The Observer responds to the client request only after its own state has caught up with the client’s state ID, which it previously received from the Active NameNode.
+
+Clients can explicitly invoke a new client protocol call msync(), which ensures that subsequent reads by this client from an Observer are consistent.
+
+A new client-side ObserverReadProxyProvider is introduced to provide automatic switching between Active and Observer NameNodes for submitting respectively write and read requests.

+* [HADOOP-16732](https://issues.apache.org/jira/browse/HADOOP-16732) | *Major* | **S3Guard to support encrypted DynamoDB table**
+
+Support server-side encrypted DynamoDB table for S3Guard. Users don't need to do anything (provide any configuration or change application code) if they don't want to enable server side encryption. Existing tables and the default configuration values will keep existing behavior, which is encrypted using Amazon owned customer master key (CMK).
+
+To enable server side encryption, users can set "fs.s3a.s3guard.ddb.table.sse.enabled" as true. This uses Amazon managed CMK "alias/aws/dynamodb". When it's enabled, a user can also specify her own custom KMS CMK with config "fs.s3a.s3guard.ddb.table.sse.cmk".

+
+The page size for bulk delete operations has been reduced from 1000 to 250 to reduce the likelihood of overloading an S3 partition, especially because the retry policy on throttling is simply to try again.
+
+The page size can be set in "fs.s3a.bulk.delete.page.size"
+
+There is also an option to control whether or not the AWS client retries requests, or whether it is handled exclusively in the S3A code. This option "fs.s3a.experimental.aws.s3.throttling" is true by default. If set to false: everything is handled in the S3A client. While this means that metrics may be more accurate, it may mean that throttling failures in helper threads of the AWS SDK (especially those used in copy/rename) may not be handled properly. This is experimental, and should be [...]

+* [HADOOP-16711](https://issues.apache.org/jira/browse/HADOOP-16711) | *Minor* | **S3A bucket existence checks to support v2 API and "no checks at all"**
+
+The probe for an S3 bucket existing now uses the V2 API, which fails fast if the caller lacks access to the bucket.
+The property fs.s3a.bucket.probe can be used to change this. If using a third party library which doesn't support this API call, change it to "1".
+
+to skip the probe entirely, use "0". This will make filesystem instantiation slightly faster, at a cost of postponing all issues related to bucket existence and client authentication until the filesystem API calls are first used.
