[jira] [Created] (ACCUMULO-4361) Test race conditions in ShellServerIT

Josh Elser created ACCUMULO-4361:
------------------------------------

             Summary: Test race conditions in ShellServerIT
                 Key: ACCUMULO-4361
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4361
             Project: Accumulo
          Issue Type: Bug
          Components: test
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Minor
             Fix For: 1.7.3, 1.8.0


[~romil.choksi] found a test issue where ShellServerIT.getAuths() would intermittently fail.

This is because of the use of ZooCache inside of ZKAuthorizor. The minicluster has two tabletservers. If the shell is so unlucky to update the authorizations on one tserver but then ask for the authorizations on the other tserver, the test is subject to the propagation of the ZK watcher update to fire.

We should just switch over ShellServerIT to run a minicluster with only one tserver than try to hack around this in the test itself with retries.
