> Pig with HCatLoader partition filter does not push down valid conditions
> ------------------------------------------------------------------------
>
> Key: PIG-3594
> URL: https://issues.apache.org/jira/browse/PIG-3594
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.11.1
> Reporter: Mona Chitnis
> Fix For: 0.11.2
>
>
> When running the following pig query (script.pig) :
> A = LOAD ' my_data' USING org.apache.hcatalog.pig.HCatLoader();
> B = FILTER A by part1=='$val1' and part2 matches '$val2';
> C = FILTER B by map#'key' matches '(val3|val4)';
> DUMP C;
> > pig -useHCatalog -p val1=2013_01_01 val2=XYZ script.pig
> This results in Pig scanning all partitions inspite of filter condition.
> part1=='$val1' should have been pushed to HCatLoader even though there are
> other conditions that cannot be pushed.
