> Starting up the MapReduce JobhHistoryServer service after a clean install appears to
automatically create the /tmp directory on HDFS. However, it is created with 750 permission.
> Attempting to run MR jobs by other users results in the following permissions exception:
> {code}
> org.apache.hadoop.security.AccessControlException: Permission denied: user=cloudera,
access=EXECUTE, inode="/tmp":yarn:supergroup:drwxr-x---
> at org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.check(FSPermissionChecker.java:205)
