> 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
> Priority: Critical
>
> 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.
