Try updating the fs.adl.impl and fs.AbstractFileSystem.adl.impl values in core-site.xml: </P><PRE> &lt;property&gt; &lt;name&gt;fs.adl.impl&lt;/name&gt; &lt;value&gt;org.apache.hadoop.fs.adl.AdlFileSystem&lt;/value&gt; &lt;/property&gt; &lt;property&gt; &lt;name&gt;fs.AbstractFileSystem.adl.impl&lt;/name&gt; &lt;value&gt;org.apache.hadoop.fs.adl.Adl&lt;/value&gt; &lt;/property&gt; </PRE> Fri, 13 Jul 2018 00:00:15 GMT jts 2018-07-13T00:00:15Z
