             Summary: User intermediate-done-dir permissions should use history file permissions configuration
                 Key: MAPREDUCE-6860
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6860
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Jonathan Hung


Currently {{JobHistoryEventHandler}} creates the user intermediate-done-dir directory here: {noformat}      doneDirPrefixPath =
          FileContext.getFileContext(conf).makeQualified(new Path(userDoneDirStr));
      mkdir(doneDirFS, doneDirPrefixPath, new FsPermission(
          JobHistoryUtils.HISTORY_INTERMEDIATE_USER_DIR_PERMISSIONS));{noformat} which is hardcoded to 770. But the summary, history, and conf files under this user dir are configurable via {{mapreduce.jobhistory.intermediate-done-dir.file.permission}}. So if the configured permissions has  read/write/execute permissions for "other" users, they will still not have access to these files due to the 770 permission on the user dir.

I see two options here:
# Reuse {{mapreduce.jobhistory.intermediate-done-dir.file.permission}} as the permissions for the user dir
# Create a new config for the user dir permissions, using 770 as the default
