Jian He commented on YARN-3348: ------------------------------- Thanks Varun, some comments: - “Unable to fetach cluster metrics” - typo - exceeding 80 Column limit, {code} opts .addOption( "types", true, "Comma separated list of types to restrict applications, case sensitive(though the display is lower case)"); {code} - the -rows, -cols options seems not having effect on my screen when I tried it, could you double check ? - the ‘yarn top’ output is repeatedly showing up on terminal every $delay seconds. it’ll be better to only show that only once. - Does the patch only show root queue info ? should we show all queues info ? - “F + Enter : Select sort field” ; may be use ’S’ for sorting ? - “Memory seconds(in GBseconds” - missing “)” - It seems a bit odd to have this method in a public API record. Do you know why hashcode is not correct without this method ? Or we can just type cast it to GetApplicationsRequestPBImpl and use the method from there. {code} // need this otherwise the hashcode doesn't get generated correctly request.initAllFields(); {code} - for the caching in ClientRMService. Do you think we can do the cache on client side ? that’ll save RPCs, especially if we have many top commands running on client side. > Add a 'yarn top' tool to help understand cluster usage > ------------------------------------------------------ > > Key: YARN-3348 > URL: https://issues.apache.org/jira/browse/YARN-3348 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Reporter: Varun Vasudev > Assignee: Varun Vasudev > Attachments: apache-yarn-3348.0.patch, apache-yarn-3348.1.patch > > > It would be helpful to have a 'yarn top' tool that would allow administrators > to understand which apps are consuming resources. > Ideally the tool would allow you to filter by queue, user, maybe labels, etc > and show you statistics on container allocation across the cluster to find > out which apps are consuming the most resources on the cluster. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
