Subject [jira] [Commented] (HBASE-7948) client doesn't need to refresh meta while the region is opening
Date Thu, 07 Mar 2013 05:38:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13595565#comment-13595565

ramkrishna.s.vasudevan commented on HBASE-7948:
-----------------------------------------------

One quick question,
Unless the META is updated asking the client to go to the new RS how is the client trying
to do some operation on the region in the new RS?
So is it like the patch is trying to handle the case where the updateToMeta has happened but
still not removed from the RIT on the RS side, which means there are two steps after meta
update
-> Change znode to RS_ZK_OPENED
-> remove from RIT.
If the patch is addressing the following case then how does this affect the end client?  So
the operation will fail till the RIT on the RS side is removed.
