Gianmarco De Francisci Morales commented on PIG-2583:
-----------------------------------------------------
Probably it is fine anyway.
The order in which they are defined (and printed) will tell you that D got
defined before A.
One use case I see for this history command is to build a Pig script
interactively step by step.
The output of the history can be then copy-pasted to a file to save the script.
In this case you would need to repeat the D = ... statement anyway to get the
correct order.
To do this for more than one statement you could simply use the output of
history, and copy-paste it in grunt up to (excluding) the last A = ...
statement.
