Answer / Harpal Singh
To view only the top 15 records from a text file (student.txt) in the HDFS directory, you would first need to load the data into Pig, and then use the LIMIT operator to limit the number of rows returned. Here is an example:
A = LOAD 'hdfs://namenode/path/to/student.txt' AS (name:chararray, age:int, grade:float);
B = LIMIT A BY 15;
