------------------------------------
Ok, are you saying you want to do more testing? In that case, I will wait for
now.
> LimitOptimizer is applied before PartitionFilterOptimizer

> Key: PIG-3410
> URL: https://issues.apache.org/jira/browse/PIG-3410
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.11.1
> Reporter: Aniket Mokashi

>
> Consider following script-
> {code}
> hcat_load = LOAD 'X' using org.apache.hcatalog.pig.HCatLoader();
> hcat_filter = FILTER hcat_load BY (part='Y');
> hcat_limited = limit hcat_filter 5;
> dump hcat_limited;
> {code}
> This script is not benefited from LimitOptimizer (pushing limit to loadfunc)
> because LimitOptimizer is applied before PartitionFilterOptimizer.
