    Description

      SparkCollector is used to collect the rows generated by HiveMapFunction or HiveReduceFunction. It currently is backed by a ArrayList, and thus has unbounded memory usage. Ideally, the collector should have a bounded memory usage, and be able to spill to disc when its quota is reached.
