e2e test harness needs to be able to compare to previous version of Pig
-----------------------------------------------------------------------
Key: PIG-1950
URL: https://issues.apache.org/jira/browse/PIG-1950
Project: Pig
Issue Type: New Feature
Components: tools
Reporter: Alan Gates
Assignee: Alan Gates
Priority: Minor
Currently the e2e test harness can work either against a database or it can
compare against canned results. We should also give an option to use an old
version of Pig to test against. This has value for two cases. One, for
scripts that cannot be tested against tested against a SQL database we do not
have to carry the expected results. Two, we can use it for compatibility
testing between versions.
