Yuanbo Liu updated HDFS-16559:
------------------------------
Summary: Seperate IBR thread waiting time from heart beat waiting time.
(was: Adding new configuration for IBR thread)
> Seperate IBR thread waiting time from heart beat waiting time.
> --------------------------------------------------------------
>
> Key: HDFS-16559
> URL: https://issues.apache.org/jira/browse/HDFS-16559
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Yuanbo Liu
> Priority: Major
>
> 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.
