Unable to start ZKFC


Unable to start ZKFC


While trying to start ZKFC from Ambari, its failing with the below error:

resource_management.core.exceptions.ExecutionFailed: Execution of ' su hdfs -l -s 
/bin/bash -c 'ulimit -c unlimited ; /usr/hdp/ --config /usr/hdp/
--daemon start zkfc'' returned 1. ERROR: Cannot set priority of zkfc process 2866

Does anybody know a solution,

Thanks in advance

@ManjunathK Can you check the jars in the hadoop class /usr/hdp/ in the problematic node and see if there is any 0 bytes file. If yes, then copy all the jars from working node and started the services.
