Plamen Jeliazkov commented on HDFS-13399:
-----------------------------------------
I looked into the unit test failure.
When the timeout struck on
{{TestStateAlignmentContextWithHA.testMultiClientStatesWithRandomFailovers}} it
left dangling DFSClients that interrupted and bleed into other unit tests. I
was able to reproduce these same errors and some new ones by reducing the
timeout in that test to just 3000 (3 seconds).
I have modified {{TestStateAlignmentContextWithHA}} so that in the {{@Before}}
case it will now kill all Workers if they are not already closed / empty.
I am now able to isolate just the failure of
{{testMultiClientStatesWithRandomFailovers}}.
I have also addressed the unused imports. Oops.
Attaching patch.

> In HDFS-12977, DFSClient's constructor was altered to make use of a new
> static method in Client that allowed one to set an AlignmentContext. This
> work is to remove that static field and make each DFSClient pass it's
> AlignmentContext down to the proxy Call level.
