Erik Krogen commented on HDFS-14406: ------------------------------------ I don't have time to take a full look at the patch today, but will give my 2c on this question: {quote} Kept this per user per user per method metrics. What do you guys think of this idea? {quote} I don't think per-user per-method metrics are a good idea. In my current system, just wading through the overall system list of per-method metrics is a daunting task. For installations with large user counts (100s or 1000s) this will make these metrics completely unusable due to their huge volume. > Add per user RPC Processing time > -------------------------------- > > Key: HDFS-14406 > URL: https://issues.apache.org/jira/browse/HDFS-14406 > Project: Hadoop HDFS > Issue Type: Improvement > Affects Versions: 3.2.0 > Reporter: Xue Liu > Assignee: Xue Liu > Priority: Minor > Fix For: 3.2.0 > > Attachments: HDFS-14406.001.patch, HDFS-14406.002.patch, > HDFS-14406.003.patch, HDFS-14406.004.patch, HDFS-14406.005.patch, > HDFS-14406.006.patch > > > For a shared cluster we would want to separate users' resources, as well as > having our metrics reflecting on the usage, latency, etc, for each user. > This JIRA aims to add per user RPC processing time metrics and expose it via > JMX. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
