Ming Ma created HDFS-7491: ----------------------------- Summary: Add incremental blockreport latency to DN metrics Key: HDFS-7491 URL: https://issues.apache.org/jira/browse/HDFS-7491 Project: Hadoop HDFS Issue Type: Improvement Reporter: Ming Ma Priority: Minor
In a busy cluster, IBR processing could be delayed due to NN FSNamesystem lock and cause NN to throw NotReplicatedYetException to DFSClient and thus increase the overall application latency. This will be taken care of when we address the NN FSNamesystem lock contention issue. It is useful if we can provide IBR latency metrics from DN's point of view. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
