Hadoop namenode dies when hdfs commands are invoked

Hadoop namenode dies when hdfs commands are invoked

When i try 'hadoop fs -ls' command in my cloudera quickstart I am facing the below error.


18/09/29 12:41:29 WARN ipc.Client: Failed to connect to server: quickstart.cloudera/ try once and fail. Connection refused
at Method)
at org.apache.hadoop.ipc.Client$Connection.setupConnection(


I noticed that the status of my namenode is 'FAILED'. After restart, I confirmed that the namenode is up and again tried with 'hadoop fs -ls' and namenode again went for failed status. So what i find is that when i try with hadoop command my namenode fails. 


Please let me know on any solution for this issue.
