How can I stop one region server out of three safely? (scale in region servers)

[Jinyeon Lee]

Hi all,

I ran one master and three region servers on EC2.

When I stopped one region server,
($HBASE_HOME/bin/hbase-daemon.sh stop regionserver)

I couldn't query in HBase shell. It returns error.

Can I scale in region servers?

Best Regards,
