[SPARK-18959] the new leader will lost the statistics of the driver's
resource on the worker.
I deploy the standalone cluster with two masters. and utilizing ZooKeeper
to provide leader election and some state storage. Firstly, I submit the
application with cluster mode. Then I kill the leader, and the standby master
will be the leader. But the new leader will lost the statistics of the driver's
resource. So I stop the application, we will see the negative used resource at
the worker from masterPage.

spark.jars support jar url with http protocal. However, if the url contains
any query strings, the "localName = name.split("/").last" won't get the
expected jar, then "val url = new File(SparkFiles.getRootDirectory(),
localName).toURI.toURL" will get invalid url. The bug fix is the same as
