Subject [jira] [Commented] (HBASE-11059) ZK-less region assignment
Date Wed, 23 Apr 2014 22:44:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11059?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13979034#comment-13979034

Jimmy Xiang commented on HBASE-11059:
-------------------------------------

bq. Table state isn't transient state, is it?
It's not. But it can be saved in this table too.
bq. Would client need to access this table to find out about assignment/state?
Should not. Since the information is already in the master memory, it will be more efficient
to ask the master directly.

> It seems that most people don't like region assignment with ZK (HBASE-5487), which causes
many uncertainties. This jira is to support ZK-less region assignment. We need to make sure
this patch doesn't break backward compatibility/rolling upgrade.
