Try The below solutions. @myzard Can you compare the values of hive.heapsize on this cluster that seem to be the issue? Please adjust them depending on the memory the HiveServer2 Heap Size automatically shows you the memory available to the cluster so i.e on my 24 GB single node I dedicated 8 GB for hive.heapsize and it fires up! Possible SLotion: 1. Increase the llap queue resource percentage 2. Try restarting YARN service and then restarted HS2I

@vinod_artga To resolve this issue, open /opt/cloudera/cm/bin/gen_credentials.sh for editing and add the following to the very end of the script: exit ${PIPESTATUS[0]} And then try generating Kerberos credentials once more. If it fails again, you should see much more detail assisting in troubleshooting. This will be addressed in a future release of Cloudera Manager.
