+* [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").

+* [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.
