What is difference between hadoop and hdfs command line tools? : <p>I see that <code>hadoop</code> and <code>hdfs</code> command line tools can perform identical operations. For example I can run <code>example.jar</code> using</p>

<pre><code>hadoop jar example.jar
</code></pre>

<p>And the same using</p>

<pre><code>hdfs -jar example.jar
</code></pre>

<p>What is difference between these two command line tools?</p>
