----------------------------------
+1 (nonbinding). Looks like a simple enough change.

> The directory /tmp/logs, where the aggregated logs go, is supposed to be read
> by JHS. But if it is not created beforehand, it will be created by
> NodeManager with the group being the superuser set in HDFS. Files created
> under this directory will then inherit the supergroup as their groups. This
> leads to JHS to fail to read the container logs files under that directory if
> JHS is not running as a user that belongs to superuser.
