Hadoop mkdir and ls commands

I did fresh setup of hadoop2.9.

To create a directory, I tried:

> hadoop fs -mkdir test 
mkdir: 'test': No such file or directory

To list its content, I tried:

> hadoop fs -ls/ 
not listing directories or files

Please help me to understand the issue.

For listing we can use

hadoop fs -mkdir /

e.g

hadoop fs -mkdir /hadoop/schema/test

For listing if its a file we can access hadoop fs -cat /

e.g

hadoop fs -cat /hadoop/schema/test.txt

Without a fully qualified path, you are required to make a user folder first

hdfs dfs -mkdir -p /user/$(whoami)
hdfs dfs -chown -R $(whoami)  /user/$(whoami)
hdfs dfs -chmod -R 750  /user/$(whoami)

Then, the first command will work so will put and ls without an otherwise fully qualified path

When you just setup hadoop, HDFS is empty. make some file and directories like below with a full path:

hadoop fs -mkdir /test
