jiajunwang opened a new pull request #363: Fix the race condition while Helix refresh cluster status cache. URL: https://github.com/apache/helix/pull/363 ### Issues #331 ### Description The design is ensuring one read only to avoid locking during the change notification. However, a later update introduced addition read. The result is that two reads may have different results because notification is lock free. This leads the cache to be in an inconsistent state. The impact is that the expected rebalance might not happen. ### Tests Running
