> 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.
