title: Where are the hadoop-examples* and hadoop-test* jars in Cloudera CDH?
body: <p>I am looking for the jar files to be able to run the hadoop jobs associated with the examples and test jars. In the past they were under /usr/lib/hadoop, but apparently no longer.  Pointers appreciated.</p>
  
  <p><strong>Note</strong>: this question was originally for CDH4.2. But some answers include info for later versions</p>
