Nihal Jain commented on HBASE-20566:
------------------------------------
{quote}I think the enabling of quota can be done in setUp() method so that we
don't need to restart the cluster twice.
{quote}
I had written the test case in a way that it does not hinder the result of any
other test cases in the given class. Enabling quota in the set up can be done,
but say we run the test class without the fix (i.e. if quota table creation
gets stuck), then none of the test cases would pass as the bug for some reasons
fails dropping of tables and rolls back. Hence will cause all test cases to
fail.

Since with the fix the test case will pass, we can surely move enabling of
quota to setUp(), but am not sure about negative scenarios. What do you suggest?

> doesn't move the table to the appropriate rs group to which system namespace
> is assigned to. Need to execute logic similar to what is done in the
> RSGroupAdminEndpoint for [post table creation|#L377] for user table creation.
> *Work Around*
> - Assigning the system table to ``default`` rsgroup (or to the rsgroup to
> which the system namespace has been assigned).
> - Manually assigning the region in RIT from the system table
