Subject [jira] [Updated] (HBASE-9730) Exceptions in multi operations are not handled correctly
Date Wed, 09 Oct 2013 02:04:42 GMT

     [ https://issues.apache.org/jira/browse/HBASE-9730?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Enis Soztutar updated HBASE-9730:

    Attachment: hbase-9730_v2.patch

v2, only contains changes to HRS. ITBLL with CM succeeded 2 iterations so far on a 7 node
cluster, versus the tests used to fail on the first iteration. So we are more confident that
this is the root cause. 

How can we write a unit test for this? 

[~saint.ack@gmail.com], [~nkeywal] do you mind taking a look?

> I think the problem is in HRegionServer.doBatchOp() where in case HRegion.batchMutate()
throws an exception, RegionActionResult indexes are not set correctly.
