Subject [jira] [Commented] (YARN-2803) MR distributed cache not working correctly on Windows after NodeManager privileged account changes.
Date Fri, 07 Nov 2014 08:24:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-2803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14201787#comment-14201787

Jian He commented on YARN-2803:
-------------------------------

just thought more, [~cwelch], I think it's fine to add a security enable conditional check
and also skip the two distributed cache tests for Windows-secuirty,  and open a follow-up
jira to either fix windows-secuirty to conform with the non-secure behavior or add a new unit
test for windows-secure-distributed-cache. what do you think ?

> This problem is visible by running {{TestMRJobs#testDistributedCache}} or {{TestUberAM#testDistributedCache}}
on Windows.  Both tests fail.  Running git bisect, I traced it to the YARN-2198 patch to remove
the need to run NodeManager as a privileged account.  The tests started failing when that
patch was committed.
