> Project: Apache Helix
> Issue Type: Improvement
> Reporter: Hunter L
> Assignee: Hunter L
> Priority: Major
>
> In isLoadBalanceDownwardForAllReplicas() in IntermediateStateCalcStage,
> statePriorityMap was throwing a NPE because the partition contained a replica
> in ERROR state, and the map did not have an entry for it. To amend the issue,
> Venice added the ERROR state in the state model with a priority, and Helix
> added checks to prevent NPEs. Changelist: 1. Add containsKey checks in
> isLoadBalanceDownwardForAllReplicas() 2. Make the Controller correctly log
> all partitions with ERROR state replicas 3. Add HelixDefinedStates in
> statePriorityList if not already added
