Nihal Jain commented on HBASE-20566:
------------------------------------
Dug a little deep. Points to note:
* During "hbase:quota" table creation, the CreateTableProcedure stays in
WAITING state as the child procedure AssignProcedure tries to assign table
regions
* The postCreateTable() hook is not reached which actually does default RS
group assignment for each table.
* None of the CreateTableProcedure hooks seem to be idle place for the logic
to add the current system table to rsgroup
Wondering where this logic should go!
> Creating a system table after enabling rsgroup feature puts in region into RIT

> Key: HBASE-20566
> URL: https://issues.apache.org/jira/browse/HBASE-20566
> Project: HBase
> Issue Type: Bug
> Components: master
> Reporter: Biju Nair
> Priority: Major
>
> *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
