Description

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:

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)
