Thank you so much for the help.

log file inside /var/log/hbase says that Error: Could not find or load main class org.hadoop.hbase.master.HMaster.

Any idea ?

I suspect that hbase is not correctly installed. When you go to /usr/hdp/current/hbase*/lib, do you find jar files? could you please list them?

@vpoornalingam

There is no jars related to Hbase.

Only ranger-hbase-plugin-impl and ranger-hbase-plugin-shim-0.5.0.2.4.0.0-169.jar available inside /usr/hdp/current/hbase-master/lib directory.

Please advise

Thanks in advance!

Are you connected to the hbase master system as listed by Ambari? If so, hbase isn't correctly installed for some reason. Is this a test cluster? If so please remove HBase using API and add it back using Ambari add service. You could refer Cwik pages for the same.

Thank you so much for the help sir.

I have done the re-installation as you suggested. Additionally i have downloaded the jar files and placed inside the /usr/hdp/current/hbase/lib folder.

the issue is fixed. Hbase master is up and running.

thank you very much for the help.

This error is because of symbolic link is broken for (Means hbase client jar is not present in the node) -

ll /usr/hdp/current/hbase-client/lib/hbase-client.jar

Put your hbase client jar from another node to the non working node-

/usr/hdp/current/hbase-client/lib/hbase-client-*.jar

Please note that, if you don't have other jars as well, then copy all the necessary missing jars from other node-

/usr/hdp/current/
