[GIRAPH-479] Factor creation of job-local ZooKeeper instances out of ZKManager to enable YARN instantiation, etc.

• Type: Improvement
• Status: Patch Available
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 1.0.0
• Component/s: zookeeper

Description

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.
