WrongRegionException should be like NSRE exception?
---------------------------------------------------
Key: HBASE-459
URL: https://issues.apache.org/jira/browse/HBASE-459
Project: Hadoop HBase
Issue Type: Bug
Components: regionserver
Affects Versions: 0.1.0, 0.2.0
Reporter: stack
Priority: Blocker
Jim was just running a loading test. It failed because of a
WrongRegionException. At first I thought it HBASE-428 -- because we were
making regions w/ same start and end key -- but looking closer, it looks like
the client is getting a WRE thought its making a legitimate request; it just
happens to be asking for a row from the top-half of a region just as it split.
I would think that on WRE, the client would at least retry in same manner in
which it does when it gets a NSRE?
Here is the split detail:
