Pig Map reduce permission denied after history server enable

I tried to enable history server using the link , I could do it only till hdfs dis -mkdir -p /app-logs as this was failing and i could not proceed.

Now when I run the pig script which is creating map reduce it is failing.with below error. nay idea?

Caused by: org.apache.hadoop.security.AccessControlException: Permission denied: user=mapred, access=READ, inode="/mr-history/tmp/hdfs/job_1459806783854_0001-1459807556718-hdfs-PigLatin%3ADefaultJobName-1459807582179-1-1-SUCCEEDED-default-1459807564263.jhist":hdfs:hdfs:-rwxrwx---

From the error above it shows mapred user is trying to create a director under /. Add mapred to user group hdfs and give it permission to rwx.
