To get dfsadmin report in the federated cluster, you need to do configure core-site.xml like below.( client side)
1) Configure all the nameservices 2) Configure the fs.defaultFS to corresponding name service.. Example: If we Four name services are running in federated cluster, you can configure like following.. <property> <name>fs.viewfs.mounttable.ClusterX.link./dir2</name> <value>hdfs://ns1/dir1</value> </property> <property> <name>fs.viewfs.mounttable.ClusterX.link./dir3</name> <value>hdfs://ns2/dir2</value> </property> <property> <name>fs.viewfs.mounttable.ClusterX.link./dir4</name> <value>hdfs://ns3/dir3</value> </property> <property> <name>fs.viewfs.mounttable.ClusterX.link./dir5</name> <value>hdfs://ns4/dir4</value> </property> And if you want get admin report for ns1 and configure like below. <property> <name>fs.defaultFS</name> <value>hdfs://ns1</value> </property> Hence it will print details for ns1.. For more details check following. http://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-hdfs/ViewFs.html Hope this can answer your query.

Looks that the command hdfs dfsadmin -report should work if I want to see the whole cluster's status. But as you see, I see the message that view.fs is not HDFS file system. If I want to see part of the whole cluster, then how I could go on? could you please show me the command? Thanks!
