Don't you need to provide your class name "JavaWordCount"?

Maybe you've already checked these out. Some basic questions that come to my
mind are:
1) is this library "foolib" or "foo-C-library" available on the worker node?
2) if yes, is it accessible by the user/program (rwx)?
Thanks,
Vasu.

Hi,
We can use CombineByKey to achieve this.
val finalRDD = tempRDD.combineByKey((x: (Any, Any)) => (x),(acc: (Any, Any), x)
=> (acc, x),(acc1: (Any, Any), acc2: (Any, Any)) => (acc1, acc2))
finalRDD.collect.foreach(println)
(amazon,((book1, tech),(book2,tech)))(barns, (book,tech))(eBay,
Try to reproduce what the spark-submit shell script does, setting up the class
path etc.

While I have a preference for Scala ( not surprising as a Typesafe person), the
DataFrame API gives feature and performance parity for Python. The RDD API
gives feature parity.
So, use what makes you most successful for other reasons ;)

There is no mechanism for keeping an RDD up to date with a changing source.
However you could set up a steam that watches for changes to the directory and
processes the new files or use the Hive integration in SparkSQL to run Hive
queries directly. (However, old query results will still grow
Show us the code. This shouldn't happen for the simple process you described

You are right in tour answer to what Mohit wrote. However what Mohit seems to
be alluring but did not write properly might be different.

You are wrong in saying generally streaming works in HDFS and cassandra .
Streaming typically works with streaming or queing source like Kafka,
I have used various version of spark (1.0, 1.2.1) without any issues . Though I
have not significantly used kafka with 1.3.0 , a preliminary testing revealed
no issues .
