Hbase Master are both on standby



We have noticed on ambari that after a maintenance that both hbase masters are on "Standby" mode:


We tried without success to restart each HBase master to see if they were going to change into "Active". 

Could you please help use

Hi @Koffi  , May I know what Ambari version you are using ? And what was the change performed on those Hbase hosts ? Also can you check the Ambari server and agent logs on both the Hbase master nodes and check specifically for any JMX or ssl related error.

The Hbase Masters can be stuck on a Standby state if it is still recovering the lease on the MasterprocWALs. You can check the same by looking at the restart logs of the Hbase Masters.


Check: hdfs dfs -ls -R /apps/hbase/data/MasterProcWALs > Check How Many Files (10000)


Possible Solution: Sideline MasterProcWALs + Waiting On RecoverLease
