Ted Yu commented on HBASE-20566:
--------------------------------
I think the enabling of quota can be done in setUp() method so that we don't
need to restart the cluster twice.
On my Mac, the duration for TestRSGroups went from 182 seconds to 166 seconds.
You just need to adjust the assertion in basic test:
{code}
- //3 meta,namespace, group
- assertEquals(3, count);
+ //3 meta,namespace, rsgroup, quota
+ assertEquals(4, count);
{code}
This also proves that all assertions in previous tests still hold with quota
enabled.

> Project: HBase
> Issue Type: Bug

> *Steps to reproduce*
> - Enable {{rsgroup}} feature
> - Enable {{quota}} feature which created {{hbase::quota}} table
> - quota table region will be marked as RIT since the {{rsgroup}} for the
> table is not known
> {noformat}

> - Reason for this issue: Issue
> - [system table
> creation|https://github.com/apache/hbase/blob/061a31fad1654d9ded96d118e04c14860413fa25/hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java#L1793]
> 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
