stack commented on HBASE-19827:
-------------------------------
Its hard to write a test for this. Have to have an ongoing, hanging RPC and
then concurrently run the servercrashprocedure. There are timing and correct
context issues hard to conjure. This TestAM#testAssignWithRandExec makes it
happen every third run.
> Addendum for Flakey TestAssignmentManager

> Addendum for parent. Rather than reopen parent for third time, doing subtask.
> So, in parent, we committed two fixes for failures seen in the random
> assignment test portion of TestAssignmentManager. The second fix almost works
> but in operation, a vital piece of info has been cleared because of the order
> in which stuff runs.
