I am running the VM in pseudo mode. Due to some resource related issues (Name Node in safe mode, not able to leave) I had to format and restart the namenode of my Cloudera 4.x. I didn't have any other choice. I used the steps provided here:
Writing to HDFS could only be replicated to 0 nodes instead of minReplication (=1)
After that I am able to properly use get/put command in hdfs which means I have read/write permission. Now, when I try to submit the job, I am getting following exception.

When I searched for above exception I found multiple links stating that mapred.local.dir should be properly defined and if not set then hadoop.tmp.dir is used. I explicitly set mapred.local.dir in mapred-site.xml and given full permission to the default folder (/var/lib/hadoop-hdfs/cache). The problem still persists.
Can someone please help in solving the issue? Regards
