What is local file System

Question

I'm currently reading about hadoop and I came across this which has puzzled me.

Use the Hadoop get command to copy a file from HDFS to your local file system:

$ hadoop hdfs dfs -get file_name /user/login_user_name

What is a local file system? I understand that a HDFS partitions a file into different blocks throughout the cluster (but I know there's more to it than that). My understanding of the above command is that I can copy a file from the cluster to my personal (i.e. local) computer? Or is that completely wrong? I'm just not entirely sure what is meant by a local file system.

Answer 1

LocalFS means it may be your LinuxFS or WindowsFS. And which is not part of the DFS.

Your understanding is correct, using -get you are getting file from HDFS to Local FS and you cannot use both hadoop and hdfs. Command should be like below

hdfs dfs -get file_name local_path or hadoop fs -get file_name local_path
