Subject [jira] [Commented] (HBASE-11370) SSH doesn't need to scan meta if not using ZK for assignment
Date Wed, 25 Jun 2014 23:44:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11370?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14044185#comment-14044185
] 

Jimmy Xiang commented on HBASE-11370:
-------------------------------------

For now, during the migration, these two column values could be different, because some region
server could run old code that can update the meta directly.  After the migration, since we
don't override the column value, they could be different if the region is moving to another
region server. Of course, I think we can override the column value after migration.

> If we don't use ZK for assignment, the meta content should be the same as that in memory.
So we should be able to avoid a meta scan.
