Under section Note it is to inform that groupId has been changed since 2.9.1
release. It doesn't mean that Kundera over HBase would require Cassandra as
well!

I can't seem to reproduce in unit test.
The main difference is that I'm using bulk load in the cluster and Put API

You can use the hbck utility to repair these kinds of problems.
$ hbase hbck -repair

Before using -repair or any other parameter, I will recommend you to run it
without any parameter to have a sense of what hbck will find.

In src/main//java/org/apache/hadoop/hbase/thrift/generated/Hbase.java , I
found the following scannerOpen() methods:
public int scannerOpen(ByteBuffer tableName, ByteBuffer startRow,
ListByteBuffer columns, MapByteBuffer,ByteBuffer attributes) throws
IOError, org.apache.thrift.TException;
Thanks for the reply Ted. I am using Hbase-sharp dll which is portd with
kind-of old scannerOpen() method which has no MapByteBuffer,ByteBuffer
attributes parameter.
I have also generated c# code from new Thrift server in which I am getting 4
arguments as you have listed.

Our usage of hbase is pretty dummy and in many cases, time stamp is used as the

If you might have more than one security enabled Java process running under
the same UNIX user on the servers, then this and other weirdness can happen
because they share the same ticket cache file in /tmp. Someone does a
(re)login and another process concurrently accessing the cache gets garbage
I forgot to ask the version of HBase you're using.
merge_region command is not available in 0.94.x
