ramkrishna.s.vasudevan updated HBASE-6152:
------------------------------------------
Attachment: HBASE-6152_0.94.patch
Test case to reproduce this issue. Infact this will happen in 0.92.0 and
0.92.1 and not in the latest code in 0.92 or 0.94.
Now the current code
{code}
if (rs.isSplit() || rs.isSplitting()) {
{code}
does not have this line. So it should not create a problem here. It was
removed as part of HBASE-6070. Prior to this it could have happened. The same
has been reproduced in the testcase.
> Split abort is not handled properly

> I ran into this:
> 1. RegionServer started to split a region(R), but the split was taking a long
> time, and hence the split was aborted
> 2. As part of cleanup, the RS deleted the ZK node that it created initially
> for R
> 3. The master (AssignmentManager) noticed the node deletion, and made R
> offline
> 4. The RS recovered from the failure, and at some point of time, tried to do
> the split again.
> 5. The master got an event RS_ZK_REGION_SPLIT but the server gave an error
> like - "Received SPLIT for region R from server RS but it doesn't exist
> anymore,.."
> 6. The RS apparently did the split successfully this time, but is stuck on
> the master to delete the znode for the region. It kept on saying -
> "org.apache.hadoop.hbase.regionserver.SplitTransaction: Still waiting on the
> master to process the split for R" and it was stuck there forever.
