Subject [jira] [Commented] (YARN-4017) container-executor overuses PATH_MAX
Date Fri, 09 Oct 2015 09:05:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-4017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14950104#comment-14950104

Sidharta Seethana commented on YARN-4017:
-----------------------------------------

The release artifact is unrelated to this JIRA. The patch simply uses a different constant
(defined in configuration.h) instead of PATH_MAX - no additional tests are required.

[~vvasudev] , could you please review this patch? Thank you.

> Lots of places in container-executor are now using PATH_MAX, which is simply too small
on a lot of platforms.  We should use a larger buffer size and be done with it.
