             Summary: HBase_1_1_2_ClientService performance dropped due to 
accessing HBase admin upon every FlowFile transfer
                 Key: NIFI-4866
                 URL: https://issues.apache.org/jira/browse/NIFI-4866
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Koji Kawamura
            Assignee: Koji Kawamura

NIFI-4543 added 
"connection.getAdmin().getClusterStatus().getMaster().getHostAndPort()” call 
from HBase_1_1_2_ClientService.toTransitUri method in order to get HBase master 
address, which is called upon every FlowFile transfer and essentially doubles 
the traffic through the HBase connector.

The performance of our PutHBaseJSON processor dropped to 1/3 after deploying 
NiFi 1.5.0.

Those lines of code should be moved from toTransitUri to createConnection.
