> Key: TWILL-63
> URL: https://issues.apache.org/jira/browse/TWILL-63
> Project: Apache Twill
> Issue Type: Improvement
> Components: yarn
> Affects Versions: 0.2.0-incubating
> Reporter: Terence Yim
> Assignee: Shankar Selvam
> Fix For: 0.7.0-incubating
>
>
> Currently when launching an application, two new jars are always created
> locally, one for AM (appMaster.jar) and one for Container (container.jar) and
> copied to HDFS before submitting the application. The jar files could
> potentially be big and if it doesn't changed, it should require copying to
> HDFS again.
