> IBR opeeration is seperated from heartbeat thread since HDFS-16016, which is
> great.
> But IBR thread is using the expireTime of heart beat to deside whether wait
> or not. In a high load DataNode, IBR thread becomes an infinit loop without
> sleeping and consuming 100% cpu because of the latency of heartbeat reporting.
