Karthiek created HELIX-553:
------------------------------
Summary: While enqueueing a job, task framework should create
state model "Task" if it doesn't already exist
Key: HELIX-553
URL: https://issues.apache.org/jira/browse/HELIX-553
Project: Apache Helix
Issue Type: Bug
Reporter: Karthiek
Task framework expects the "Task" state model to be already defined. Otherwise
enqueueing a job using ClusterTask framework throws this exception:
org.apache.helix.HelixException: State model Task not found in the cluster

Existing clusters will not have "Task" state model already defined. It would be
really great if the task framework automatically creates it if the state model
doesn't exist.
