Description

When submitting a driver using spark-submit in cluster mode, Spark 1.1.0 allowed you to omit the file:// or hdfs:// prefix from the application JAR URL, e.g.

./bin/spark-submit --deploy-mode cluster --master spark://joshs-mbp.att.net:7077 --class org.apache.spark.examples.SparkPi /Users/joshrosen/Documents/old-spark-releases/spark-1.1.0-bin-hadoop1/lib/spark-examples-1.1.0-hadoop1.0.4.jar

In Spark 1.1.1 and 1.2.0, this same command now fails with an error:

./bin/spark-submit --deploy-mode cluster --master spark://joshs-mbp.att.net:7077 --class org.apache.spark.examples.SparkPi /Users/joshrosen/Documents/Spark/examples/target/scala-2.10/spark-examples_2.10-1.1.2-SNAPSHOT.jar
Jar url 'file:/Users/joshrosen/Documents/Spark/examples/target/scala-2.10/spark-examples_2.10-1.1.2-SNAPSHOT.jar' is not in valid format.
Must be a jar file path in URL format (e.g. hdfs://XX.jar, file://XX.jar)

Usage: DriverClient [options] launch <active-master> <jar-url> <main-class&gt; [driver options]
Usage: DriverClient kill <active-master> <driver-id>

I tried changing my URL to conform to the new format, but this either resulted in an error or a job that failed:

./bin/spark-submit --deploy-mode cluster --master spark://joshs-mbp.att.net:7077 --class org.apache.spark.examples.SparkPi file:///Users/joshrosen/Documents/Spark/examples/target/scala-2.10/spark-examples_2.10-1.1.2-SNAPSHOT.jar
Jar url 'file:///Users/joshrosen/Documents/Spark/examples/target/scala-2.10/spark-examples_2.10-1.1.2-SNAPSHOT.jar' is not in valid format.
Must be a jar file path in URL format (e.g. hdfs://XX.jar, file://XX.jar)

If I omit the extra slash:

./bin/spark-submit --deploy-mode cluster --master spark://joshs-mbp.att.net:7077 --class org.apache.spark.examples.SparkPi file://Users/joshrosen/Documents/Spark/examples/target/scala-2.10/spark-examples_2.10-1.1.2-SNAPSHOT.jar

This bug effectively prevents users from using spark-submit in cluster mode to run drivers whose JARs are stored on shared cluster filesystems.
