Subject [jira] Created: (HBASE-1920) Client with cached region location pointing at dead server does not recover
Date Tue, 20 Oct 2009 00:06:59 GMT
Client with cached region location pointing at dead server does not recover
---------------------------------------------------------------------------

                 Key: HBASE-1920
                 URL: https://issues.apache.org/jira/browse/HBASE-1920
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.20.1
            Reporter: Jonathan Gray
            Priority: Critical
             Fix For: 0.20.2, 0.21.0


Testing in HBASE-1908 uncovered an issue where I had a client that had cached a region location.
 I killed that regionserver, waited for recovery/reassignment, and then tried to scan the
table again from the same client w/o restarting it.

A client normally gets a NotServingRegionException when a region is reassigned, but since
this server is dead the client just got Connection Refused type exceptions.  These didn't
seem to trigger the client to ask META for a new region location.
