Ming Ma updated HDFS-7491: -------------------------- Attachment: HDFS-7491.patch Here is the patch to add IBR latency to DataNodeMetrics. > 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 > Attachments: HDFS-7491.patch > > > 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)
