> Introduce a new config property (something like _yarn.service.framework.path_ in-line
with _mapreduce.application.framework.path_) for YARN Service dependency tarball location.
This will provide flexibility to the user/cluster-admin to upload the dependency tarball
to a location of their choice. If this config property is not set, YARN Service client will
default to uploading all dependency jars from the client-host's classpath for every service
launch request (as it does today).
> Also, accept an optional destination HDFS location for *-enableFastLaunch* command,
to specify the location where user/cluster-admin wants to upload the tarball. If not specified, let's
default it to the location we use today. The cluster-admin still needs to set _yarn.service.framework.path_
to this default location otherwise it will not be used. So the command-line will become something
like this -
> {code:java}
> yarn app -enableFastLaunch [<Destination Folder>]{code}
