Hey,

In Apache pig, the LOAD statement will simply load the data into the specified relation. To verify the execution of the Load statement you have to use the Diagnostic operators. Pig Latin provides four different types of Diagnostic operator, they are:

  • Dumb operator
  • Describe operator
  • Explanation operator 
  • Illustration operator
