Kadir OZDEMIR commented on PHOENIX-5986:
----------------------------------------
[~ckulkarni] checkCurrentResult is not used.
It is interesting that the child link table records are dropped but the syscat
table still has some records for these child views. In this test, the base
table has two levels of child views. We need to have two task runs to delete
both levels. To remove all the child links we need only one task run. In the
second run, the leaf child views are removed. Either in the second task run no
action is taken or somehow the query on the syscat table returns some stale
cache data. Maybe we can add more logging to both SelfHealingTask and
DropChildViewsTask to see if the second run does something at all.

> I also see that the test sometimes fails because it expects task status to
> be COMPLETED, but sees status to be STARTED instead.
