GlenGeng opened a new pull request #1676: URL: https://github.com/apache/ozone/pull/1676
## What changes were proposed in this pull request? Add ReadWriteLock into PipelineStateManagerV2Impl to protect contentions between RaftServer and PipelineManager. If current leader SCM (as leader of term N) steps down while there are on-going transactions, there might be read/write contentions that new leader SCM (as leader of term N+1) has replicated some raft log entries encapsulating method addPipeline()/removePipeline()/updatePipelineState() to the underlying RaftServer that are being applied by StateMachineUpdater, and at the same time PipelineManager is calling getPipelines(). ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-4560 ## How was this patch tested?
