If you want to get the summary from a cluster, I'm thinking you can use
"-fs" option to specify the NameNode of the cluster. The command will be
"hdfs dfsadmin -fs hdfs://nn1:port -report".
dfsadmin -report does not support reporting the summary of all the
cluster mounted on a viewfs.

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..

Thanks Chinnappan for the quick reply!
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!

Hi, our hadoop cluster is using HDFS Federation, but when use the
following command to report the HDFS status
It gives me the following message that viewfs is NOT HDFS filesystem
Then how can I proceed to report the hdfs status
Thanks!
[admin@namenode1]$ ./hdfs dfsadmin -report
report: FileSystem viewfs://nsX/ is not an HDFS file system
Usage: hdfs dfsadmin [-report] [-live] [-dead] [-decommissioning]
