Resolution: Duplicate
> helix controller not sending/delay sending transition messages
> --------------------------------------------------------------
>
> Key: HELIX-265
> URL: https://issues.apache.org/jira/browse/HELIX-265
> Project: Apache Helix
> Issue Type: Bug
> Reporter: Zhen Zhang
> Assignee: Zhen Zhang
>
> we are seeing a couple of cases where the participant is using leader-standby
> state model, and after controller sends OFFLINE->STANDBY transitions, it
> doesn't sending STANDBY->LEADER transitions for a long time (more than 30
> minutes). During the 30 minutes, we are seeing controller rebalancer pipeline
> runs more 4000 times on that particular cluster.
> a few observation:
> 1) No GC happens on Helix participant, helix controller, and zk server
> 2) lots of ideal-state changes and controller/rebalancer pipeline is super
> busy
> we can't reproduce this
