Please try the below steps, this can happen if /tmp mount point is mounted with noexec option... - Create a new directory under any directory(ex /data/tmp) with exec permission and to test provide 777 permissions for newly created dir.
- Update the config in zeppelin config as below and restart the zeppelin.
CM UI --> Zeppelin --> Config --> "Zeppelin Server Advanced Configuration Snippet (Safety Valve) for zeppelin-conf/zeppelin-env.sh" --> Add export ZEPPELIN_JAVA_OPTS="-Djava.io.tmpdir=<directory name>"
example: export ZEPPELIN_JAVA_OPTS="-Djava.io.tmpdir=/data/tmp"
- Save changes and restart zeppelin server and verify the login

I am able to solve the issue. The issue was that my keytab was not proper. I guess the keytab was corrupted, not sure what is the reason. After generating a new keytab, my Storm service is up and running.

I found the issue. My Ranger admin and ranger database reside on different nodes. I was giving the database host instead of Ranger admin host in "policymgr_external_url" property. Correcting it solved the issue. Thanks for your reply.
