Troubleshooting an HBase Connection Configured for Clusters that Do Not Use Kerberos Authentication

Troubleshooting an HBase Connection Configured for Clusters that Do Not Use Kerberos Authentication

I got a valid Kerberos ticket when I configured a Kerberos connection in the Developer client to connect to the HBase master server that uses Kerberos authentication. Later when I used the same setup and disabled the Kerberos authentication to connect to a cluster that does not use secure authentication, the connection failed.
The error occurs because the mode of authentication in the
hive-site.xml
configuration set does not update and the same ticket that was generated for a Kerberos cluster is used for the cluster that does not use Kerberos authentication. To resolve the issue, perform the following steps:
  1. Refresh the cluster configuration in the Administrator tool.
  2. Extract the cluster configuration archive files to the following location on the Developer tool machine:
    <Informatica installation directory>\clients\DeveloperClient\hadoop\<Hadoop distribution>\conf
  3. Restart the Developer tool.
