Apache Pig ORDER BY Operator

The Apache Pig ORDER BY operator sorts a relation based on one or more fields. It maintains the order of tuples.

Example of ORDER BY Operator

In this example, we return only two tuples from all the tuples in the relation.

Steps to execute ORDER BY Operator

• Create a text file in your local machine and insert the list of tuples.

• Check the tuples inserted in the text files.

• Upload the text files on HDFS in the specific directory.

• Open the pig MapReduce run mode.

• Load the file that contains the data.

• Now, execute and verify the data.

• Let's return the first two tuples.

Here, we got the desired output.
