James Kinley commented on HBASE-7442:
-------------------------------------

Please see attached patch.

The first option was actually quite messy to implement. {{clusterId}} and 
{{conf}} are fixed in *{{HBaseClient}}* when it's created and cached by 
*{{SecureRpcEngine}}*, so to implement the fix here I would have had to pass 
the different cluster {{confs}} up through *{{HConnectionManager}}* and 
*{{HBaseRPC}}* in order to override the clusterId in 
*{{SecureClient#SecureConnection}}*.

I've gone with the second option of creating and caching different 
*{{SecureClients}}* for the local and remote clusters in *{{SecureRpcEngine}}* 
- keyed off of the {{clusterId}} instead of the default *{{SocketFactory}}*. I 
think this is a cleaner solution.

Please let me know what you think.

> When security is enabled, HBase CopyTable fails with Kerberos exception:
> {code}
> FATAL org.apache.hadoop.ipc.SecureClient: SASL authentication failed. The 
> most likely cause is missing or invalid credentials. Consider 'kinit'.
> javax.security.sasl.SaslException: GSS initiate failed [Caused by 
> GSSException: No valid credentials provided (Mechanism level: Failed to find 
> any Kerberos tgt)]
> {code}
> This is only when copying to remote HBase cluster (using either MRv1 or 
> YARN), local copy works fine.
