Revert "HBASE-24579: Failed SASL authentication does not result in an exception on client side (#1921)" This reverts commit bd79c4065ccb13a5e217d844376b3e7b9489d2fe. When Kerberos authentication succeeds, on the server side, after receiving the final SASL token from the client, we simply wait for the client to continue by sending the connection header. After HBASE-24579, on the client side, an additional readStatus() was added, which mistakenly assumes that after negotiation has completed a status code will be sent. However when authentication has succeeded the server will not send one. As a result the client will hang and only throw an exception when the configured read timeout is reached, which is 20 seconds by default. We cannot unilaterally send the expected additional status code from the server side because older clients will not expect it. The first call will fail because the client finds unexpected bytes in the stream ahead of the call response. Fabricating a call response also does not seem a viable strategy for backwards compatibility. The HBASE-24579 change needs to be reconsidered given the difficult backwards compatibility challenges here. -- This is an automated message from the Apache Git Service.
