> Reporter: Sammi Chen
> Priority: Major

> The DN is found no response to the /jmx request. And with further
> investigation, this DN failed to join the new pipeline at the same time.
> Attached is the jstack, it seems that DN is waiting for the
> RaftServerProxy$ImplMap LOCK to add new group, while the LOCK is hold by
> another thread to remove the old group, and this thread wants to have the
> readLock of it's SegmentLock, the readLock is hold by another writeChunk
> thread, which is waiting stateMachineDataCache quota.
> See the attached jstack.
