HA: use substitution token for fencing argument
-----------------------------------------------

                 Key: HADOOP-8007
                 URL: https://issues.apache.org/jira/browse/HADOOP-8007
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: ha
    Affects Versions: HA Branch (HDFS-1623)
            Reporter: Eli Collins
            Assignee: Eli Collins


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.
