Appy created HBASE-17681:
----------------------------

             Summary: Simplify ssh and 'Operation Not Permitted' issues when our IT tests
execute monkeys
                 Key: HBASE-17681
                 URL: https://issues.apache.org/jira/browse/HBASE-17681
             Project: HBase
          Issue Type: Improvement
            Reporter: Appy
            Assignee: Appy

Executing remote command: ps ux | grep proc_regionserver | grep -v grep | tr -s ' ' | cut
-d ' ' -f2 | xargs kill -s SIGKILL , hostname:appy2-5.vpc.cloudera.com
util.Shell: Executing full command [/usr/bin/ssh  appy2-5.vpc.cloudera.com "sudo -u hbase
ps ux | grep proc_regionserver | grep -v grep | tr -s ' ' | cut -d ' ' -f2 | xargs kill -s
SIGKILL"]
{noformat}

The issue with above command is:
- kill commands runs as the ssh'ed user, and if it's not hbase, it has to be root
- which means, that either hbase or root needs to have passwordless access setup to all the
other hosts of the cluster, which may not be true in many cases.

Generalizing it a bit so that it can also work with a setup when there is a user (\*any\*
user) in the cluster with passwordless access to other nodes, and sudo permissions.
