Spark file system watcher not working on Windows

Two people tested Apache Spark on their computers...

[Spark Download - http://i.stack.imgur.com/z1oqu.png]

We downloaded the version of Spark prebuild for Hadoop 2.6, went to the folder /spark-1.6.2-bin-hadoop2.6/, created a "tmp" directory, went to that directory, and ran:

$ bin/run-example org.apache.spark.examples.streaming.HdfsWordCount tmp

I added arbitrary files content1 and content2dssdgdg to that "tmp" directory.

-------------------------------------------
Time: 1467921704000 ms
-------------------------------------------
(content1,1)
(content2dssdgdg,1)

-------------------------------------------
Time: 1467921706000 ms

Spark detected those files with the above terminal output on my Ubuntu 15.10 laptop, but not on my colleague's Windows 7 Enterprise laptop.

This is preventing us from getting work done with Spark.
