Subject [jira] [Commented] (YARN-5456) container-executor support for FreeBSD, NetBSD, and others if conf path is absolute
Date Tue, 02 Aug 2016 23:17:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15404998#comment-15404998

Allen Wittenauer commented on YARN-5456:
----------------------------------------

I have a Kerberized Ubuntu/x86 VM that I generally use for testing things.  Popped trunk+this
patch onto it.  Looks like things are working the way they are supposed to.

Ran a simple sleep streaming job and ended up with the following dirs in the nm-local-dir:
{code}
root@ku:/tmp/hadoop-yarn/nm-local-dir# find . -user aw -type d -ls
  9367    4 drwxr-s---   4 aw       yarn         4096 Aug  2 16:08 ./usercache/aw
  9368    4 drwxr-s---   3 aw       yarn         4096 Aug  2 16:08 ./usercache/aw/appcache
  9370    4 drwxr-s---   7 aw       yarn         4096 Aug  2 16:08 ./usercache/aw/appcache/application_1470179247859_0001
{code}

after job finished, directories disappeared as expected.

> YARN-5121 fixed quite a few portability issues, but it also changed how it determines
it's location to be very operating specific for security reasons.  We should add support for
FreeBSD to unbreak it's ports entry, NetBSD (the sysctl options are just in a different order),
and for operating systems that do not have a defined method, an escape hatch.
