Bill Graham updated PIG-2574:
-----------------------------
Attachment: pig-2574_4.patch
Here's a patch with Dmitriy's comments, plus a few other small edits:
* Incorporated the fix from PIG-2616 into {{InputSizeReducerEstimator}}.
* Added both {{@InterfaceAudience.Public}} and {{@InterfaceStability.Evolving}}
to {{PigReducerEstimator}}.
* Moved some tests from {{TestJobControlCompiler}} to
{{TestInputSizeReducerEstimator}}.
Also, I added the following to {{.gitignore}}. Let me know if I should back
that out and put it in it's own patch:
{noformat}
+target/
+*.iml
+*.ipr
+*.iws
{noformat}
> Make reducer estimator plugable
