--------------------------------
Summary: TaskDriver#enqueueJob need add Task state model
definition if not already in cluster
Key: HELIX-566
URL: https://issues.apache.org/jira/browse/HELIX-566
Project: Apache Helix
Issue Type: Bug
Reporter: Zhen Zhang
The Task state model definition is a new state model we add recently for
TaskFramework. For the old cluster settings where Task state model definition
is missing, TaskDriver#enqueueJob might throw an exception when creating the
ideal-state for the job but successfully add the job to the queue in the
Workflow config.
This leaves the workflow/job config/status inconsistent and may blocks job from
being scheduled.
We need to check in TaskDriver#enqueueJob that if Task state model definition
is missing, it will add it to the cluster.
