> projcets
> --------------------------------------------------------------------------------
>
> Key: YARN-2464
> URL: https://issues.apache.org/jira/browse/YARN-2464
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Siddharth Seth
> Assignee: Junping Du
>
> DEFAULT_YARN_APPLICATION_CLASSPATH are used by YARN projects to setup their
> AM / task classpaths if they have a dependency on Hadoop libraries.
> It'll be useful to provide similar access to a Hadoop tarball (Hadoop libs,
> native libraries) etc, which could be used instead - for applications which
> do not want to rely upon Hadoop versions from a cluster node. This would also
> require functionality to update the classpath/env for the apps based on the
> structure of the tar.
> As an example, MR has support for a full tar (for rolling upgrades).
> Similarly, Tez ships hadoop libraries along with it's build. I'm not sure
> about the Spark / Storm / HBase model for this - but using a common copy
> instead of everyone localizing Hadoop libraries would be useful.
