Michael Armbrust 778a0548cc [SPARK-7548] [SQL] Add explode function for DataFrames ... Add an `explode` function for dataframes and modify the analyzer so that single table generating functions can be present in a select clause along with other expressions. There are currently the following restrictions: - only top level TGFs are allowed (i.e. no `select(explode('list) + 1)`) - only one may be present in a single select to avoid potentially confusing implicit Cartesian products.
