Spark file system watcher not working on Windows
<p>Two people tested <a href="http://spark.apache.org/downloads.html" rel="nofollow noreferrer">Apache Spark</a> on their computers...</p>

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

<pre><code>$ bin/run-example org.apache.spark.examples.streaming.HdfsWordCount tmp
</code></pre>

<p>I added arbitrary files <code>content1</code> and <code>content2dssdgdg</code> to that "tmp" directory.</p>

<pre><code>-------------------------------------------
Time: 1467921704000 ms
-------------------------------------------
(content1,1)
(content2dssdgdg,1)

-------------------------------------------
Time: 1467921706000 ms
</code></pre>

<p>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.</p>

<p>Does Spark's file system watcher not work on Windows?</p>
