The dfsadmin is run like below

Get a report of status from each name node to show that the name nodes are in Safe Mode or not.

$ hdfs dfsadmin -D 'fs.default.name=hdfs://mycluster/' -safemode get 

A report that shows the details of HDFS state:

$ hdfs dfsadmin -D 'fs.default.name=hdfs://mycluster/' -report 

Get HDFS out of safe mode

$ hdfs dfsadmin -D 'fs.default.name=hdfs://mycluster/' -safemode leave

What's is your HDInsight cluster name

This is the format of the hdfsadmin command in Azure, where mycluster is your cluster name

hdfs dfsadmin -D "fs.default.name=hdfs://mycluster/" -report

Can you give the output of this command

hadoop fs -ls wasb://yourcontainer@youraccount.blob.core.windows.net/

The following is a list of configurations that should be modified to configure WASB: I assume you have done the below

fs.defaultFS

wasb://<containername>@<accountname>.blob.core.windows.net 

fs.AbstractFileSystem.wasb.impl

org.apache.hadoop.fs.azure.Wasb 

fs.azure.account.key. blob.core.windows.net

storage_access_key

So I can see you have only the user paplcloudamin home directory set

Can you run the following

$ hdfs dfs -D "fs.default.name=hdfs://mycluster/" -mkdir /test

Check if the directory was created, you should be able to see test directory

$ hdfs dfs -D "fs.default.name=hdfs://mycluster/" -ls /

This command should run successfully,can you just copy and paste this command replacing my cluster with your clustername

$ hdfs dfsadmin -D "fs.default.name=hdfs://mycluster/" -report

Please revert

Re: how to check the dfsadmin report in wasb space

$ hdfs dfs -D "fs.default.name=wasb://containername@storage_name.blob.core.windows.net//"-mkdir /test

Done

$ hdfs dfs -D "fs.default.name=wasb://containername@storage_name.blob.core.windows.net/"-ls /

Result:
drwxr-xr-x - paplcloudadmin supergroup 0 2018-04-02 09:33 /test

hdfs dfsadmin -D "fs.default.name=wasb://containername@storage_name.blob.core.windows.net/" -report

I'm getting the same error. This is the response I received form Cloudera support "Only the dfs commands such as ls/put/mv etc works on wasb using the wasb connector. Admin commands such as dfsadmin as well fsck works only with native hadoop/hdfs implementation"
