Gera Shegalov created MAPREDUCE-5875: ----------------------------------------
Summary: Make Counter limits consistent conf across JobClient, MRAppMaster, and YarnChild Key: MAPREDUCE-5875 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5875 Project: Hadoop Map/Reduce Issue Type: Bug Components: applicationmaster, client, task Affects Versions: 2.4.0 Reporter: Gera Shegalov Assignee: Gera Shegalov Currently, counter limits "mapreduce.job.counters.*" handled by {{org.apache.hadoop.mapreduce.counters.Limits}} are initialized asymmetrically: on the client side, and on the AM, job.xml is ignored whereas it's taken into account in YarnChild. It would be good to make the Limits job-configurable, such that max counters/groups is only increased when needed. With the current Limits implementation relying on static constants, it's going to be challenging for tools that submit jobs concurrently (e.g. via class loading isolation). The patch that I am uploading is not perfect but demonstrates the issue. -- This message was sent by Atlassian JIRA (v6.2#6252)
