Assuming you are in Linux based OS

Create a file using: $ nano /path/to/file.txt .

You must have sufficient priviledge in directory where you create the file.

To move the file to HDFS ( As a user privileged to access HDFS, say hdfs user ) :

hadoop fs -put /path/to/file.txt

To check the file : hadoop fs -ls /user/<hadoop user>

To check the content of file : hadoop fs -cat /user/<hadoop user>/file.txt

Now you can create a Hive table using create external table .. and mention the path of file in HDFS.
