---------------------------------
Summary: Adding new configuration for IBR thread
Key: HDFS-16559
URL: https://issues.apache.org/jira/browse/HDFS-16559
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Yuanbo Liu
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.
