Wellington Chevreuil commented on HBASE-24579:
----------------------------------------------
Merged into master, branch-2 and branch-2.3 branches. Tried to cherry pick into
branch-2.2 but got compile errors in TestHBaseSaslRpcClient. [~bszabolcs], can
you make a PR to branch-2.2?
> Failed SASL authentication does not result in an exception on client side

> When HBaseSaslRpcClient.saslConnect tries to authenticate it only reads the
> input stream if the process is not complete yet. However if the
> authentication failed and the process is completed the exception sent back in
> the stream never gets read.
> We should always try to read the input stream even if the process is complete
> to make sure it was empty.
