I’m new to hadoop and I’m trying to create a directory in hdfs called input_dir. I have set up my vm, installed and started hadoop successfully.
This is the command that I run:
hdfs dfs -mkdir input_dir
And it keeps returning this error message:
mkdir: 'hdfs://hongdao-master:9000/user/hadoophongdao': No such file or directory
Why is it giving this error?

You need to first hadoop fs mkdir -p /user/hadoophongdao && hadoop fs -chmod -R 760 /user/hadoophongdao
Your user folder is used as the default parent folder without providing an absolute path, and it’s not created by default for any user of HDFS.
Otherwise, you could use /tmp/input_dir
