-------------------------------
Summary: add gapplyCollect() for SparkDataFrame
Key: SPARK-16012
URL: https://issues.apache.org/jira/browse/SPARK-16012
Project: Spark
Issue Type: Sub-task
Components: SparkR
Affects Versions: 1.6.1
Reporter: Sun Rui
Add a new API method called gapplyCollect() for SparkDataFrame. It does gapply
on a SparkDataFrame and collect the result back to R. Compared to gapply() +
collect(), gapplyCollect() offers performance optimization as well as
programming convenience, as no schema is needed to be provided.
This is similar to dapplyCollect().
