Plamen Jeliazkov updated HDFS-13665:
------------------------------------
Description:
In HDFS-13399 we addressed a race condition in AlignmentContext processing
where the RPC response would assign a transactionId independently of the
transactions own processing, resulting in a stateId response that was lower
than expected.

At the end it was agreed upon to move the logic of Server.setupResponse into
Server.doResponse directly.
