Answer / Amit Anand
In Apache Pig, to get the top 10 tuples from a relation, you can use the TOP operator. Here's an example:nn`DEFINE myUDF MyUserDefinedFunction();ndata = LOAD 'input_data' AS (col1: chararray, col2: int, col3: float);ntop_data = FOREACH data GENERATE *;ntop_data = TOP top_data 10;nSTORE top_data INTO 'output_data';`
