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

             Summary: Factor creation of job-local ZooKeeper instances out of ZKManager to
enable YARN instantiation, etc.
                 Key: GIRAPH-479
                 URL: https://issues.apache.org/jira/browse/GIRAPH-479
             Project: Giraph
          Issue Type: Improvement
          Components: zookeeper
    Affects Versions: 0.2.0
            Reporter: Eli Reisman
            Assignee: Eli Reisman
            Priority: Minor


When the user does not specify a ZooKeeper quorum to run Giraph on, the ZooKeeperManager creates
one. This factors out the boilerplate that handles this additional process and its lifecycle
so that various pluggable versions of this process instantiation can be implemented and fed
to the ZKManager via a factory depending on the nature of the underlying cluster.

By implementing the ZooKeeperProcessBuilder interface, one will now be able to implement the
creation/mangement of a new, job-local ZK instance using any underlying resourcing mechanism
one chooses (including, I hope, YARN.)

Passes mvn verify, etc.
