Subject [jira] [Commented] (YARN-5287) LinuxContainerExecutor fails to set proper permission
Date Wed, 27 Jul 2016 03:06:22 GMT

    [ https://issues.apache.org/jira/browse/YARN-5287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15394986#comment-15394986

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

Thanks Naganarasimha and Rohith for review. I've updated the patch with addressing Rohith's
comment. Please have a look.
The test failure is not related, separate code path. And I've seen YARN-5425 has already been
filed against it. Although what's interesting is that the test failure seems to be similar
with what we are trying to resolve here.

> 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
