Subject [jira] [Commented] (YARN-4594) container-executor fails to remove directory tree when chmod required
Date Tue, 09 Feb 2016 20:17:18 GMT

    [ https://issues.apache.org/jira/browse/YARN-4594?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15139679#comment-15139679
] 

Chris Nauroth commented on YARN-4594:
-------------------------------------

This patch broke compilation on Mac OS X 10.9, where the SDK does not include a definition
of {{AT_REMOVEDIR}} in fcntl.h or unistd.h.  If you have the 10.10 SDK installed, then the
header does have {{AT_REMOVEDIR}}.  (See /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/sys/fcntl.h).
 I haven't yet figured out if there is an easy way Mac users can set it to cross-compile with
the 10.10 SDK as a workaround.  For now, I'm just going to have to skip this part of the build
on Mac.

> test-container-executor.c doesn't work:
> * It assumes that realpath(/bin/ls) will be /bin/ls, whereas it is actually /usr/bin/ls
on many systems.
> * The recursive delete logic in container-executor.c fails -- nftw does the wrong thing
when confronted with directories with the wrong mode (permission bits), leading to an attempt
to run rmdir on a non-empty directory.
