+ Adds a JAR dependency for Spark tasks to be executed in the future.
+ The `path` passed can be either a local file, a file in HDFS (or
other Hadoop-supported
+ filesystems), an HTTP, HTTPS or FTP URI, or local:/path for a file
on every worker node.
+ If `addToCurrentClassLoader` is true, add the jar to the current
threads' class loader

class loader will impact all

their class loader.
