SOLUTION FOUND: since we copy the data from unsecure cluster to secure cluster we need to set the property "ipc.client.fallback-to-simple-auth-allowed" to true in the secured cluster. We added the host entries of the unsecured cluster in the secured cluster. Now everything is working fine!

Thanks for the alternatives Wes Floyd, It works one way again. WEB HDFS : Yes WEBHDFS works from cluster A again. From Cluster B we use a numeric UserID because of which webhdfs call is failing, I see a patch for this anyways https://issues.apache.org/jira/browse/HDFS-4983. Is this patch not available as part HDP 2.4 ! Other cases: We tried to add -fs option same result Most weird part is hadoop fs -ls hdfs://a.a.a.a:8020, it still not throwing error it still gives the values of the cluster B. Extra Cluster Info: Cluster B has WanDisco installed, is this setup causing any issue. I hope we use WanDisco fusion client Jar instead of the hadoop Jars at the backend. Any pointers here! core_site.xml Entries: <property>
<name>fs.hdfs.impl</name>
<value>com.wandisco.fs.client.FusionHdfs</value>
</property> <property>
<name>fusion.handshakeToken.dir</name>
<value>##SOME DIR##</value>
</property> <property>
<name>fusion.ihc.http.policy</name>
<value>HTTP_ONLY</value>
</property> <property>
<name>fusion.ihc.ssl.enabled</name>
<value>true</value>

More info. on the cluster: we have cluster A & B. cluster A - HDP 2.3 - not kerberised cluster B - HDP 2.4 - kerberised Action: we are trying to list the directories in cluster A by issuing the command from one of the client machine of cluster B. "hadoop fs -Dfs.defaultFS=<A namenode IP:port> -ls / " OR "hadoop fs -ls hdfs://<A namenode IP:port>/" we are able to list the directories of cluster B from cluster A client machine. Expectation Result: should list the directories from cluster A HDFS Actual Result: we are getting the list of files in the current B instead of cluster A. Reverse listing is working fine! Request: Please provide some pointers on what could have been the issue to enable -D option or what actually is stopping us to list the directories in the remote cluster.
