Xiaoqiao He commented on HDFS-16016:
------------------------------------
Thanks involve me here. It is good idea. I just wonder if meet some performance
issue?
IIUC, it only includes heartbeat, IBR and FBR request from DataNode to NameNode
now. All commands processed has been asynchronous. AND FBR is one low frequency
request.
Heartbeat/IBR are both send from DataNode to NameNode, I do not heartbeat is
blocked by IBR in my practice, would you mind offer some more log/information
if meet this case? Thanks again.
> BPServiceActor add a new thread to handle IBR
