> Parent directory permission could be wrong while create done_intermediate

> Key: MAPREDUCE-7427
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7427
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobhistoryserver
> Affects Versions: 3.3.4
> Reporter: Zhang Dongsheng
> Priority: Major
>
> When creating "history/done_intermediate", we seem to assume that the parent
> directory of the folder exists and has the correct permissions. But when I
> run it, it doesn't work. When the umask is too strict, the permission of the
> parent directory will be wrong. Even under the default umask, the permission
> of the parent directory cannot be guaranteed to be 777. This is because the
> "history/done_intermediate" directory needs to be accessed by mapred, and the
> user when the directory was created The group information is user1 and
> supergroup, so mapred will access it as other user. It can be seen that at
> the time of creation, only the permission setting of the last-level directory
> is concerned (setPermission will only take effect for the last-level path),
> and no permission is set for the parent path. In this patch, I have given
> permissions to its parent path through the stack
