Subject [jira] [Commented] (YARN-7333) container-executor fails to remove entries from a directory that is not writable or executable
Date Mon, 16 Oct 2017 19:25:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7333?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16206438#comment-16206438
] 

Nathan Roberts commented on YARN-7333:
--------------------------------------

Thanks for the patch Jason. 
A couple of comments:
- Log line with "failed to unlink symlink" now applies to things that aren't symlinks
- Log line with "is_symlink_helper" should say "is_dir_helper"

I'm +1 after these small tweaks.

> Similar to the situation from YARN-4594, container-executor will fail to cleanup directories
that do not have write and execute permissions for the directory.  YARN-4594 fixed the scenario
where the directory is not readable, but it missed the case where we can open the directory
but either not traverse it (i.e.: no execute permission) or cannot remove entries from within
it (i.e.: no write permissions).
