What Vaibhav said; just take out the regionservers gently by shutting each
down using hbase-daemon.sh stop -- preferably not the hosts carrying -ROOT-
and .META if you can avoid it (less churn if you don't have to take these
down). Once down and their regions are deployed elsewhere, you'll want to
Rolling Restart would be the best option in my opinion.

Hello,
I am trying to take down 9 nodes out of our 20 node Hadoop/HBase cluster. What
is the best way to do this without having to shut down the entire cluster and
have things to continue to run without a hiccup?
Thank you in advance,
