Microsoft® HDInsight Preview for Windows: How to create a directory in Hadoop File System?

Standard

In this post, we’ll see how to create a directory in the Hadoop File System for HDInsight’s windows version.

Here are the steps:

1. You have the Microsoft® HDInsight Preview for Windows Installed on your machine. Here’s a tutorial: Installing HDInsight (Microsoft’s Hadoop) on windows 7

2. Make sure that the Cluster is up & running! To check this, I click on the “Microsoft HDInsight Dashboard” or open http://localhost:8085/ on my machine

Did you get any “wait for cluster to start..” message? No? Great! Hopefully, all your services are working perfectly and you are good to go now!

3. Let’s start the Hadoop Command Line (can you see the Icon on the Desktop? Yes? Great! Open that!)

4. Here the command to create a directory looks like:

hadoop fs -mkdir /user/data/input

The above command creates /user/data/input

5. Let’s verify that the input directory was created under /user/data

hadoop fs -ls /user/data

hadoop file system list files in a directory create directory

Conclusion:
In this post, we saw how to create a directory in Hadoop (on windows) file system and also we saw how to list files/directory using the -ls command.
