Search in a String (ENDSWITH) – Apache Pig

We frequently look for a certain term in a string. This sort of search is feasible in most programming languages that support wild-card searches. In Apache Pig, there is a method that allows us to search for a keyword in a string.

The functions STARTSWITH and ENDSWITH tests inputs to determine if the first argument ends with the string in the second. We are going to discuss about “ENDSWITH” in this article.

Let’s do some practice exercises for better understanding.

Sample data:

The below data contains year of the movie released and the movie title. Save this data in a CSV file.

Loading data into a relation
rawdata = LOAD ‘Desktop/Docs/movies.csv’ USING PigStorage() as (data:chararray);

Splitting the data using ENDSWITH function.

moviedata = FOREACH rawdata GENERATE ENDSWITH(data, ‘Hide’);

Retrieve data.
DUMP moviedata;


If you look at the above data and output, you’ll see that one row out of ten is TRUE because the sought term was located there.

This function is beneficial in real-time circumstances where we are confronted with a significant example or criterion.
