But, Is there any way to control the process of storing specific rows on

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
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 res
toString() and
