Subject [jira] [Commented] (HBASE-5882) Prcoess RIT on master restart can try assigning the region if the region is found on a dead server instead of waiting for Timeout Monitor
Date Fri, 18 May 2012 09:40:09 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13278670#comment-13278670

ramkrishna.s.vasudevan commented on HBASE-5882:
-----------------------------------------------

The latest test case failure in TestAssignmentManager is due to the impact of the testcase
that went in HBASE-5927.  A small tweak will make it work.

> Currently on  master restart if it tries to do processRIT, any region if found on dead
server tries to avoid the nwe assignment so that timeout monitor can take care.
> This case is more prominent if the node is found in RS_ZK_REGION_OPENING state. I think
we can handle this by triggering a new assignment with a new plan.
