[jira] [Updated] (YARN-7333) container-executor fails to remove entries from a directory that is not writable or executable

     [ https://issues.apache.org/jira/browse/YARN-7333?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe updated YARN-7333:
-----------------------------
    Attachment: YARN-7333.001.patch

Attaching a patch that avoids opening the file unless we believe it is a directory and then calls chmod to fix permissions if the user doesn't have read, write, and execute permissions on it.

> 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).
