Andrew Purtell updated HBASE-19708:
-----------------------------------
Description:
Rare NPE when the listener's accept channel is closed. We serialize access to
related state to avoid a previously fixed related NPE and need to do the same
for {{acceptChannel}}. Seen in a 0.98 deploy but I think applicable to later
code lines. Let me check.
Exception in thread "MetadataRpcServer.handler=191,queue=0,port=60020"
