> Cache Yarn jars in GobblinYarnAppLauncher
> -----------------------------------------

> Key: GOBBLIN-2135
> URL: https://issues.apache.org/jira/browse/GOBBLIN-2135
> Project: Apache Gobblin
> Issue Type: Improvement
> Reporter: William Lo
> Priority: Major
> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> Gobblin YARN Application Launcher lacks some functionality used in
> MRJobLauncher. One of the biggest gaps in feature parity is the absence of
> jar caching, where MRJobLauncher creates a monthly cache that is
> automatically cleaned up by subsequent executions performed 2 months in
> advance.
> YARN/MR requires uploading jars to HDFS, this step can be quite slow (~15
> mins for a sizeable job to get all the jars), and given that many jobs do
> share the same jars, it makes sense to cache them together and only provide
> YARN the shared path.
> We also want to ensure that SNAPSHOT jars are other files are not uploaded to
> a cache, since they are not immutable unlike jar versions on Artifactory.
