Mikhail Antonov commented on HBASE-13103: ----------------------------------------- TestRegionServerObserver failure is unrelated, javadoc & checkstyle will be fixed in v1 patch > [ergonomics] add region size balancing as a feature of master > ------------------------------------------------------------- > > Key: HBASE-13103 > URL: https://issues.apache.org/jira/browse/HBASE-13103 > Project: HBase > Issue Type: Brainstorming > Components: Usability > Reporter: Nick Dimiduk > Assignee: Mikhail Antonov > Attachments: HBASE-13103-v0.patch > > > Often enough, folks miss-judge split points or otherwise end up with a > suboptimal number of regions. We should have an automated, reliable way to > "reshape" or "balance" a table's region boundaries. This would be for tables > that contain existing data. This might look like: > {noformat} > Admin#reshapeTable(TableName, int numSplits); > {noformat} > or from the shell: > {noformat} > > reshape TABLE, numSplits > {noformat} > Better still would be to have a maintenance process, similar to the existing > Balancer that runs AssignmentManager on an interval, to run the above > "reshape" operation on an interval. That way, the cluster will automatically > self-correct toward a desirable state. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
