RaftServerProxy$ImplMap LOCK not available
Key: HDDS-5721
URL: https://issues.apache.org/jira/browse/HDDS-5721
Project: Apache Ozone
Issue Type: Bug
Reporter: Sammi Chen
The DN is found no response to the /jmx request. And with further
investigation, this DN failed to join the new pipeline at the same time.
Attached is the jstack, it seems that DN is waiting for the
RaftServerProxy$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.
