I suppose that would work. (I'll try it.) But I was thinking more along the lines of "rec.clear()".

I'm planning to use an Avro GenericRecord (GenericData.Record) inside a Hadoop Reducer, and it would be much better from a memory usage perspective if I could just clear the record's contents at the beginning of every reduce() call, rather than having to instantiate a new one for each call. Any way to make this happen? (And if no, anyone think this is something important enough that I should file a bug report on this?) Thanks, DR
