Jiandan Yang created HDFS-14045: ------------------------------------ Summary: Use different metrics in DataNode to better measure latency of heartbeat/blockReports/incrementalBlockReports of Active/Standby NN Key: HDFS-14045 URL: https://issues.apache.org/jira/browse/HDFS-14045 Project: Hadoop HDFS Issue Type: Improvement Components: datanode Reporter: Jiandan Yang
Currently DataNode uses same metrics to measure rpc latency of NameNode, but Active and Standby usually have different performance at the same time, especially in large cluster. For example, rpc latency of Standby is very long when Standby is catching up editlog. We may misunderstand the state of HDFS. Using different metrics for Active and standby can help us obtain more precise metric data. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
