 Key: HBASE-5781
 URL: https://issues.apache.org/jira/browse/HBASE-5781
 Project: HBase
  Issue Type: Bug
  Components: hbck
Affects Versions: 0.90.7, 0.92.1, 0.94.0, 0.95.2
Reporter: Kristam Subba Swathi
Assignee: Jonathan Hsieh
Priority: Critical
 Fix For: 0.92.2, 0.94.0

 Attachments: hbase-5781.patch


 After running the hbck in the cluster ,it is found that one region is not 
 assigned
 So the hbck -fix is used to fix this 
 But the assignment didnt happen since the zookeeper session is closed

Anoop, Kristam, thanks for finding this and hunting down the root cause of the 
problem.  Thanks for the quick review Lars.

Committed to 0.90/0.92/0.94.  Trunk is broken currently because of HBASE-5747,

Attachment: hbase-5781.patch

Implemented fix suggested in conversation.  Applied to 0.92.x based hbase, and 
confirmed that hbck's assignment operations worked.

* Fixed a borked test cluster
* On ok cluster, use hbase shell to closed a region, ran updated hbck to verify 
 detected, ran 'hbck -fix' to fix assignment and problem was repaired. 

Note for this to pass on trunk, HBASE-5993 is needed as well.
