Jonathan Hung resolved MAPREDUCE-6860.
--------------------------------------
Resolution: Not A Bug
> 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
> The latter makes more sense to me.
