------------------------------------

             Summary: Add netcat and fuser as dependencies for some of the Bigtop stack. 
                 Key: BIGTOP-574
                 URL: https://issues.apache.org/jira/browse/BIGTOP-574
             Project: Bigtop
          Issue Type: Bug
          Components: General
    Affects Versions: 0.3.0
            Reporter: Peter Linnell
            Priority: Minor
             Fix For: 0.4.0


The SshFenceByTcpPort class assumes that netcat (nc) and fuser will be available on the ssh
target. fuser is in /sbin and is probably always installed, but I've definitely seen CentOS
boxes without netcat installed. We could force installation by listing it as a package requirement,
which I suspect would be a good thing.
