Subject [jira] [Commented] (HBASE-11759) TableZnode should be cached
Date Fri, 15 Aug 2014 20:09:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14099027#comment-14099027

Virag Kothari commented on HBASE-11759:
---------------------------------------

Hmm..HBASE-7767 is very related and also seems to be solving a bigger problem. So, most probably
this would not be needed for trunk as it would be contained by HBASE-7767. May be we can just
have this for 0.98

>  On receiving the rpc call about Region state transition, the rpc reader threads on master
tries to figure whether the table is in disabling or disabled state. For this they all read
tableznode which becomes a point of contention. We can just cache the state of table.
