Do we need to distribute the data explicitly by any means..?
I guess that should be done automatically by load balancer of Hbase , right?
Please someone help me..!

I setup hbase cluster on two machines. One machine has master aswell as
regionserver and other has only RS. After running ./start-hbase.sh all
daemons are started perfectly. But 2nd machine which runs only RS is
getting disconnceted after some time and what ever data i iserted in to
Hbase table
Hi all,
Facing problem with Hbase region server disconnecting with master after
some time. I set up Hbase cluster with 2 machines where Machine-1 (M1) is
master and Region server and M2 is only Region server.
After running hbase-start.sh , all the daemons are started perfectly but
after some time
basic regexs for validation. Or you could consider using a
more structured serialization format like protobufs.

Startcode is used to distinguish between the start-ups of same
regionserver at different time point.
It's the start-time of one regionserver.
