Restarting of Namenode failed with error as it could not find the mysql connector jar. Similar failure happened with the HBase Master and region servers as well.
This happened when I installed ranger through ambari and have installed in a 4 node cluster with below set up:
Node2: Ranger, mySQL
Node3: Namenode, HBase Master, HBase Region
Node4: HBase Region
After copying the mysql-connector-java.jar to the namenode and HBase servers, able to start them successfully.
So the question I have is, is it necessary for the Ranger admin to be installed on the same node as the Namenode and the HBase Master?
OK, so the mysql-connector-java.jar has to be installed manually on the Namenode and HBase Servers?
