Subject [jira] [Commented] (YARN-3000) YARN_PID_DIR should be visible in yarn-env.sh
Date Fri, 02 Jan 2015 18:02:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-3000?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14263091#comment-14263091
] 

Allen Wittenauer commented on YARN-3000:
----------------------------------------

It's worth pointing out that YARN_PID_DIR is effectively deprecated in trunk.  The variable
is still honored, but HADOOP_PID_DIR is documented and used as the default.

> YARN_PID_DIR should be visible in yarn-env.sh

> Currently I see YARN_PID_DIR only show in yarn-deamon.sh which is supposed not the place
for user to set up enviroment variable. IMO, yarn-env.sh is the place for users to set up
enviroment variable just like hadoop-env.sh, so it's better to put YARN_PID_DIR into yarn-env.sh.
( can put it into comment just like YARN_RESOURCEMANAGER_HEAPSIZE )
