Chris Trezzo commented on MAPREDUCE-6690:
-----------------------------------------
bq. should there be a corresponding YARN feature to reject applications that
are asking for too much localization?
Yes, totally agree. As per the description, I was thinking of creating a follow
up jira for a more complete server-side YARN solution. I am thinking of
something where we can leverage the container launch context and the node
manager can be smart about not launching containers that will cause too much
localization. I haven't thought too much about this yet, but I will definitely
file the jira.

> Users will sometimes submit a large amount of resources to be localized as
> part of a single map reduce job. This can cause issues with YARN localization
> that destabilize the cluster and potentially impact other user jobs. These
> resources are specified via the files, libjars, archives and jobjar command
> line arguments or directly through the configuration (i.e. distributed cache
> api). The resources specified could be too large in multiple dimensions:
> # Total size
> # Number of files
> # Size of an individual resource (i.e. a large fat jar)
> We would like to encourage good behavior on the client side by having the
> option of enforcing resource limits along the above dimensions.
> There should be a separate effort to enforce limits at the YARN layer on the
> server side, but this jira is only covering the map reduce layer on the
> client side. In practice, having these client side limits will get us a long
> way towards preventing these localization anti-patterns.
