[jira] [Updated] (HBASE-28158) Decouple RIT list management from TRSP invocation
[ https://issues.apache.org/jira/browse/HBASE-28158?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Kyle Purtell updated HBASE-28158:
----------------------------------------
Description:
Operators bypassed some in progress TRSPs leading to a state where some regions were persistently in transition but hidden. Because the master builds its list of regions in transition by tracking TRSP, the bypass of TRSP removed the regions from the RIT list.
Although I can see from reading the code this is the expected behavior, it is surprising for operators and should be changed. Operators expect that regions that should be open but are not appear the master's RIT list, provided by /rits.jsp, the output of the shell's 'rit' command, and in ClusterStatus.
We should only remove a region from the RIT map when assignment reaches a suitable terminal state.
