Usually some edits in <STRONG>/etc/hosts</STRONG> help. If you are performing a manual install of the agent, verify the ambari host it's pointing to in its ini file.</P> Mon, 21 Dec 2015 21:21:22 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Error-while-Installing-HDFS-using-Ambari-tool/m-p/100268#M13176 andrewg 2015-12-21T21:21:22Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Error-while-Installing-HDFS-using-Ambari-tool/m-p/100269#M13177 <P><A rel="user" href="https://community.cloudera.com/users/1662/parinitakothari.html" nodeid="1662">@Parinita Kothari</A> </P> Sat, 06 Feb 2016 04:20:15 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Error-while-Installing-HDFS-using-Ambari-tool/m-p/100269#M13177 aervits 2016-02-06T04:20:15Z
