Subject [jira] Created: (PIG-625) Add global -explain, -illustrate, -describe mode to PIG

Add global -explain, -illustrate, -describe mode to PIG

                 Key: PIG-625
                 URL: https://issues.apache.org/jira/browse/PIG-625
             Project: Pig
          Issue Type: New Feature
            Reporter: Yiping Han

Currently PIG has the command EXPLAIN, ILLUSTRATE and DESCRIBE. But user need to manually
add/remove these lines in the script when they want to debug or see details of the job. I
think there should be a wait to enable these globally. 

What I suggest is, to add -explain, -illustrate, -describe options to PIG command line. When
either of these are presented, all the DUMP and STORE commands in the script are converted
into EXPLAIN, ILLUSTRATE, DESCRIBE correspondingly. This makes debugging easier.
