Subject [jira] [Commented] (HBASE-12035) Keep table state in META
Date Tue, 10 Feb 2015 16:10:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12035?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14314390#comment-14314390

stack commented on HBASE-12035:
-------------------------------

[~octo47] It does not apply to master branch.

patching file hbase-server/src/test/java/org/apache/hadoop/hbase/HBaseTestingUtility.java
Reversed (or previously applied) patch detected!  Assume -R? [n]

Maybe it includes something that was just committed.  I can fix in a hour or so but maybe
you want to do it meantime.  Post a branch-1 patch too if you have a chance.  No harm if you
do not get to it, I'll have a go myself latter this morning.  Thanks.

> HBASE-7767 moved table enabled|disabled state to be kept in hdfs instead of zookeeper.
isTableDisabled() which is used in HConnectionImplementation.relocateRegion() now became a
master RPC call rather than a zookeeper client call. Since we do relocateRegion() calls everytime
we want to relocate a region (region moved, RS down, etc) this implies that when the master
is down, the some of the clients for uncached regions will be affected. 
> See HBASE-7767 and HBASE-11974 for some more background.
