Istvan Toth commented on HBASE-29843:
-------------------------------------
Phoenix overrides _hbase.rpc.controllerfactory.class_ with its own
implementations , which overrides setPriority(final TableName tn) to set its
own priorities.
The Async RPC code uses ConnectionUtils, instead of HBaseRpcController to set
the prioirity, so the custom Phoenix priority code never gets run.
this is one Phoenix RPCController that is used on branch-2, but is not called
on branch-3:
[https://github.com/apache/phoenix/blob/master/phoenix-core-client/src/main/java/org/apache/hadoop/hbase/ipc/controller/MetadataRpcController.java]
> HBaseRPCController.setPriority(final TableName tn) is never called on
> branch-3+
