graceful_stop.sh not found in HDP2.1 Hbase

I was reading Hortonworks documenrtation to remove regionserver from any host of cluster (http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.1-latest/bk_system-admin-guide/content/admin_decommission-slave-nodes-3.html). It uses graceful_stop.sh script . The same script is described at Apache Hbase book (https://hbase.apache.org/book/node.management.html)

I was trying to find this script but not able to locate it .

hbase@node ~]$ ls /usr/lib/hbase/bin/
draining_servers.rb   hbase.cmd         hbase-daemon.sh  region_status.rb  test
get-active-master.rb  hbase-common.sh   hbase-jruby      replication
hbase                 hbase-config.cmd  hirb.rb          start-hbase.cmd
hbase-cleanup.sh      hbase-config.sh   region_mover.rb  stop-hbase.cmd
[hbase@node ~]$

Is this script is removed from hbase ?

Is there any other way to stop a region server from anyother host of cluster. For eg - I want to stop region server 1 . Can I do this by logging into region server2?

Yes, the script is removed from hbase if you use package install. But you can still find it in src files.

If you want to stop a region server A from another host B, then host B must have privilege to access A. e.g. You have added public key of host B to authorized_keys in A. For a typical cluster, a RS cannot login to other RS directly for security.

For how to write graceful_stop.sh by yourself, you can look at: https://groups.google.com/a/cloudera.org/forum/#!topic/cdh-user/fA3019_vpZY
