Re: ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 Times
Dear Jimmy,

I configured the standalone mode successfully. But I wonder why the pseudo
distributed one does work.

I checked in logs and got the following exceptions. Does the information
give you some hints?

Thanks so much for your help again!
