  • Ensure that we have a file named wikitechy_math.txt in the HDFS directory /pig_data/. This file contains integer and floating point values as given below.


  • You have loaded this file into Pig with a relation named math_data as given below.
grunt> math_data = LOAD 'hdfs://localhost:9000/pig_data/wikitechy_math.txt' USING PigStorage(',')
   as (data:float);
  • Now you can generate the hyperbolic sine values of the contents of the wikitechy_math.txt file using SINH() function as given below.
grunt> sinh_data = foreach math_data generate (data), SINH(data);


Verify the contents of the relation using the Dump operator as given below.

grunt> Dump sinh_data;


  • The above statement stores the result in the relation named sinh_data.
