Description
Currently when running spark on yarn, jars specified with --jars, --packages will be added twice, one is Spark's own file server, another is yarn's distributed cache, this can be seen from log:
for example:
./bin/spark-shell --master yarn-client --jars examples/target/scala-2.11/jars/scopt_2.11-3.3.0.jar
If specified the jar to be added is scopt jar, it will added twice:

Actually it is not necessary to add into Spark's file server. This problem exists both in client and cluster modes, and it is introduced in SPARK-15782 to fix the --packages not work in spark-shell.
