Hello,
I am running a ycsb instance to insert data into hbase.All was well when
this was against hbase 0.96.1.Now I am trying to run the same program to
another cluster which is configured with hbase 0.98.4.I get the below

Do you have replication turned on in hbase and if so is your slave
consuming the replicated data?.

Hey folks,
I am trying to write a map reduce in pig against my hbase table.I have a
salting in my rowkey appended with reverse timestamps ,so I guess the best
way is to do a scan for all the dates that I require to pull out
records.Does any one know if pig supports hbase scan out of the box or
It doesn't support dealing with salted rowkeys (or reverse timestamps) out
of the box, so you may have to munge with the data a little bit after it's
loaded to get what you want.
Hope this helps.

What version of HBase you are using?
You can try clear the ZNode about regionserver list in zookeeper

the dead region

Can you telnet to port 2181 and 60020 on the remote cluster if you are
running default ports.I had a similar issue in the past where there was

For bulk imports you can create HFiles directly and add them incrementally:

tool moves files, not copies them. So once written you
will not do any additional writes (except for those regions which was split
while you filtering data). If importing data is small that would not be a
problem.
