Subject [jira] [Commented] (YARN-5026) Container fail to launch for mapred application
Date Mon, 02 May 2016 18:13:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-5026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15267150#comment-15267150
] 

Robert Kanter commented on YARN-5026:
-------------------------------------

Containers shouldn't be relying on getting their environment variables from the NodeManager.
 For compatibility, the change in https://github.com/apache/hadoop/commit/9d4d30243b0fc9630da51a2c17b543ef671d035c
was only done in trunk.  The equivalent change in branch-2, https://github.com/apache/hadoop/commit/ac8fb579c6058fec60caf30682f902413d68edf3,
does not remove _all_ of the environment variables.

> As part for launch script {{HADOOP_MAPRED_HOME}} default value is not set .After https://github.com/apache/hadoop/commit/9d4d30243b0fc9630da51a2c17b543ef671d035c
  {{HADOOP_MAPRED_HOME}} is not able to get from {{builder.environment()}} since {{DefaultContainerExecutor#buildCommandExecutor}}
sets inherit to false.
