> Key: HBASE-20566
> URL: https://issues.apache.org/jira/browse/HBASE-20566
> Project: HBase
> Issue Type: Bug
> Components: master
> Reporter: Biju Nair
> Assignee: Nihal Jain
> Priority: Major
> Fix For: 3.0.0
>
> Attachments: HBASE-20566.master.001.patch, HBASE-20566.master.002.patch

> *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}
> 2018-05-10 14:33:32,392 INFO [ProcedureExecutorThread-0] zookeeper.ZKTableStateManager: Moving table hbase:quota state from null to ENABLING

> - Reason for this 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
