Duo Zhang commented on HBASE-21644:
-----------------------------------
Maybe a possible way is that, we read the max sequence id for the primary
region when opening a secondary region replica, and when we want to reopen a
secondary replicas, we should always schedule a reopen region procedure for its
primary region, then finally the openSeqNum of the secondary region replica
will increase and we can break the infinite loop?
> Modify table procedure runs infinitely for a table having region replication

> URL: https://issues.apache.org/jira/browse/HBASE-21644
> Project: HBase
> Issue Type: Bug
> Components: Admin
> Affects Versions: 3.0.0, 2.1.1, 2.1.2
> Reporter: Nihal Jain
> Assignee: Nihal Jain
> Priority: Critical
> Attachments: HBASE-21644.master.001.patch, HBASE-21644.master.UT.patch

>
> *Steps to reproduce*
> # Create a table with region replication set to a value greater than 1
> # Modify any of the table properties, say max file size
> *Expected Result*
> The modify table should succeed and run to completion.
> *Actual Result*
> The modify table keep running infinitely
> *Analysis/Issue*
> The problem occurs due to inifinitely looping between states
> {{REOPEN_TABLE_REGIONS_REOPEN_REGIONS}} and
> {{REOPEN_TABLE_REGIONS_CONFIRM_REOPENED}} of {{ReopenTableRegionsProcedure}},
> called as part of {{ModifyTableProcedure}}.
> *Consequences*
> For a table having region replicas:
> - Any modify table operation fails to complete
> - Also, enable table replication fails to complete as it is unable to change
> the replication scope of the table in source cluster
