Zhen Zhang updated HELIX-566:
-----------------------------
Description:
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.
Helix controller needs to check (in TaskDriver#enqueueJob) that if Task state
model definition is missing, it will add it to the cluster automatically.
