How do I view an HDFS file?

The hadoop fs -ls command allows you to view the files and directories in your HDFS filesystem, much as the ls command works on Linux / OS X / *nix. A user's home directory in HDFS is located at /user/userName. For example, my home directory is /user/akbar.

What is the difference between Hadoop and HDFS?

HDFS is a Java based distributed file system that allows you to store large data across multiple nodes in a Hadoop cluster. Whereas HBase is a NoSQL database (similar as NTFS and MySQL). HBase provides low latency access to small amounts of data within large data sets while HDFS provides high latency operations.
