Viraj Jasani commented on HDFS-16016:
-------------------------------------
[~jianghuazhu] This sounds nice, curious, which part of IBR handling you think
can improve performance of rest of functionalities (i.e FBR and heartbeat)? Is
it "waitTillNextIBR()" that consumes more time in main thread of
BPServiceActor? Or is it sending IBRs to NameNode that seems bit problematic?
Or both together consumes more time?
> BPServiceActor add a new thread to handle IBR

> We can handle IBR independently to improve the performance of heartbeat and
> FBR.
