          Description

          Per HADOOP-7983 currently the fencer always passes the target host:port to fence as the first argument to the fence script, it would be better to use a substitution token. That is to say, the user would configure "myfence.sh $TARGETHOST foo bar" and Hadoop would substitute the target. This would allow use of pre-existing scripts that might have a different ordering of arguments without a wrapper.
