[jira] [Created] (HBASE-5835) [hbck] Catch and handle
NotServingRegionException when close region attempt fails
[hbck] Catch and handle NotServingRegionException when close region attempt fails
---------------------------------------------------------------------------------
Key: HBASE-5835
URL: https://issues.apache.org/jira/browse/HBASE-5835
Project: HBase
Issue Type: Bug
Components: hbck
Affects Versions: 0.90.7, 0.92.2, 0.94.0, 0.96.0
Reporter: Jonathan Hsieh
Currently, if hbck attempts to close a region and catches a NotServerRegionException, hbck may hang outputting a stack trace. Since the goal is to close the region at a particular server, and since it is not serving the region, the region is closed, and we should just warn and eat this exception.
{code}
