-------------------------------
Summary: Participant duplicated state transition handling rework
Key: HELIX-705
URL: https://issues.apache.org/jira/browse/HELIX-705
Project: Apache Helix
Issue Type: Task
Reporter: Hao Zhang
Helix should have some re-work on participant side message handling:
- Duplicated message in same batch: discard the later one
- Duplicated message in different batches, the later one should be discarded
if the first one is in progress
- During state transition, we should not rely on current state delta to get
partition's current state, but should lock on state model def (thread safety)
- Duplicated state transition (toState == currentState) should not result in
error, which is confusion, but should report success
