Gera Shegalov updated MAPREDUCE-5875:
-------------------------------------
Attachment: MAPREDUCE-5875.v02.patch
Thanks for pointing at {{JobClient.getJob}}, Robert. It's a wrapper around
{{Cluster.getJob}} and its implementation is incorrect. It uses
{{JobConf.<init>(String)}} that adds the submitted conf (job.xml) as a resource
on LocalFileSystem
{code}
conf = new JobConf(status.getJobFile());
{code}
instead of using the correct filesystem. I fixed it and added a unit test for
this scenario.
> 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
> Attachments: MAPREDUCE-5875.v01.patch, MAPREDUCE-5875.v02.patch

>
> 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 without resorting to class loading
> isolation.
> The patch that I am uploading is not perfect but demonstrates the issue.
