[~cheolsoo] I have filed this JIRA as per our conversation on user forum. If
it's alright, I would like to work on this task.
> Add counters for filter operation

> Key: PIG-4009
> URL: https://issues.apache.org/jira/browse/PIG-4009
> Project: Pig
> Issue Type: Improvement
> Components: internal-udfs
> Reporter: Abhishek Agarwal
> Priority: Minor
> Labels: features
>
> In a pig script, map input and output records would be different due to
> operations such as flatten, filter etc. In such cases, the information about
> number of records being filtered by any filter gets lost. Having counters for
> the filter operations will provide more visibility into the job.
