Subject [jira] [Commented] (YARN-5287) LinuxContainerExecutor fails to set proper permission
Date Tue, 12 Jul 2016 02:38:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-5287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15372083#comment-15372083

Ying Zhang commented on YARN-5287:
----------------------------------

I have a simple patch here. I've tested it with my 3-node cluster. It works as expected.
What the patch does is explicitly setting the required permission for each newly created local
directory.
Would someone please review the fix and see if there is anything missing? Thank you:-)

> LinuxContainerExecutor fails to set the proper permissions on the local directories(i.e.,
/hadoop/yarn/local/usercache/... by default) if the cluster has been configured with a restrictive
umask, e.g.: umask 077. Job failed due to the following reason:
> Path /hadoop/yarn/local/usercache/ambari-qa/appcache/application_xxxxxxxx has permission
700 but needs permission 750
