Liangjun He updated HDFS-17541:
-------------------------------
Description: Currently, msync requests and other client requests share the
same RPC Server on the Active NameNode. When other requests are blocked in the
RPC Server queue due to locks, it can also block msync requests, thereby
affecting the performance of OBNN. Since msync is essentially an empty request,
it is necessary for us to dedicate a separate RPC Server specifically for
handling msync requests.
