Subject [jira] [Commented] (YARN-5301) NM mount cpu cgroups failed on some systems
Date Wed, 19 Apr 2017 21:57:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-5301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15975612#comment-15975612

Daniel Templeton commented on YARN-5301:

Thanks for fixing that test, [~miklos.szegedi@cloudera.com].  Regarding the fix, is it safe
to assume that any non-Linux host is just running unit tests?  What about Windows?  I think
there are also cases where folks run Hadoop on MacOS or Solaris.
