> Currently how records are passed into the hive streaming RecordWriter are
> converted from the inbound format to Hive format is opaque. The encoding and
> writing are done in a single call to RecordWriter.write(). This is
> problematic for test tools that want to intercept the record stream and write
> it to a benchmark in addition to Hive.
> All existing RecordWriters have an encode and getSerDe methods. I propose to
> expose these by making them public in AbstractRecordWriter, and making
> AbstractRecordWriter a public class (it is currently package private). This
> keeps the RecordWriter interface clean (stream writers will not need to
> directly call these methods) and avoids any backwards incompatible changes.
> Having AbstractRecordWriter public is also desirable for anyone who wants to
> write their own RecordWriter.
