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

             Summary: Put up webserver on standby monitor instances and redirect to the active
monitor instance
                 Key: ACCUMULO-4327
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4327
             Project: Accumulo
          Issue Type: Improvement
          Components: monitor
            Reporter: Josh Elser
             Fix For: 2.0.0


Had an issue where a user was trying to access the monitor, but claimed that it wasn't listening.

After a brief debugging session, we found out that he had multiple monitors running and he
was trying to access one of the "standby" instances instead of the active one.

It would be very nice to have the webserver up all the time, but when the local monitor is
not the active instance, redirect the client to the current active monitor. All of the necessary
information should already be present in ZooKeeper -- it would just be a Jetty redirect exercise.
