Please provide log files entries from ambari, hbase and particular region server to start with.

Ambari and HDP version

OS

Is Keberos in place?

[#3 · Accepted solution]

Make sure this file => /etc/hbase/conf/hbase_client_jaas.conf is available on your Regionserver node. It is used to authenticate the regionserver.

Content should look like this:

Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=false
useTicketCache=true;
};

Do you have Kerberos enabled? @rxu
