(I am assuming that you are running HDFS command from secure cluster Node to connect to Non secure NameNode hence in that case we do not need to have kerberos ticket, But if it is vice-versa then we will need to have kerberos ticket as well)<BR /><BR />1. Please make sure that the remote clusters IP Address (and Hostname) and port is accessible ? (this is to isolate firewall blocking issue)</P><PRE># telnet 10.166.54.12 8020 # telnet $REMOTE_NN_HOSTNAME 8020</PRE><P><BR /><BR />2. Please try to specify the "--config" parameter to poiint to a directory where you have kept the HDFS configuration file of remote cluster.</P><PRE># hadoop --config /PATH/TO/Remote_Clusters fs -ls /</PRE><P><BR />Here please replace the "/PATH/TO/Remote_Clusters" with the path where you have kept the "hdfs-site.xml" and "core-site.xml" file of remote cluster.</P><P>.</P> Mon, 26 Feb 2018 20:24:53 GMT jsensharma 2018-02-26T20:24:53Z
