Subject [jira] [Commented] (HBASE-6143) Make region assignment smarter when regions are re-enabled.
Date Thu, 25 Jul 2013 03:57:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13719201#comment-13719201

Lars Hofhansl commented on HBASE-6143:
--------------------------------------

v2 *could* work. The code path for assignment after enabling is now quite different, though.

Might still be better to call {{AssignmentManager.assign(Map<HRegionInfo, ServerName>
regions)}} {{BulkEnabler.populatePool}}, I think we can build the map ahead of time.

This is the same call used by AssignmentManager.joinCluster(), so we'd use the same code.

> Right now a random region server is picked when re-enabling a table. This could be much
smarter.
