> Eliminate unbounded memory usage for orderBy and groupBy in Hive on Spark

> Currently, orderBy (sortBy) and groupBy in Hive on Spark uses unbounded
> memory. For orderBy, Hive accumulates key groups using ArrayList (described
> in HIVE-15527). For groupBy, Hive currently uses Spark's groupByKey operator,
> which has a shortcoming of not being able to spill to disk within a key
> group. Thus, for large key group, memory usage is also unbounded.
> It's likely that this will impact performance. We will profile and optimize
> afterwards. We could also make this change configurable.
