----------------------------------
Summary: support group-by collected for load funcs that don't
implement CollectableLoadFunc
Key: PIG-3007
URL: https://issues.apache.org/jira/browse/PIG-3007
Project: Pig
Issue Type: New Feature
Reporter: Thejas M Nair
group-by collected should be supported for all input that are sorted on
group-by keys.
To ensure that a map task gets all records for a group-key, indexing can be
done to determine which key at which it should start processing , and if it
should read from next split as well to get remaining records for the last
group-by column in its original split.
