--------------------------------------

             Summary: Support for 'where <regionid>' in shell to get the live and history of region location
                 Key: HBASE-23778
                 URL: https://issues.apache.org/jira/browse/HBASE-23778
             Project: HBase
          Issue Type: Improvement
            Reporter: Swaroopa Kadam
            Assignee: Swaroopa Kadam


My initial thought is mainly to extend the HBase shell(gradually extend to CLI and UI) to allow the use of 
{code:java}
where <regionid>{code}
to get the necessary information and allow passing history as an additional parameter to get the history. We can configure how many transitions we want to store so that anything (ZK or small data structure in the table region itself or maybe something else) that is used for state management is not exploded.
As pointed by
[~andrew.purtell@gmail.com] need to be watchful of mistakes done in the past: HBASE-533
