Description

The IOutputSerializer javadoc specifies that the user may optionally provide a ByteBuffer to serialize into.

https://github.com/apache/storm/blob/af42f434f4a4c3d9087c6058b359033736d3b5e8/sql/storm-sql-runtime/src/jvm/org/apache/storm/sql/runtime/IOutputSerializer.java#L26

None of the IOutputSerializer implementations we ship with actually do this. They all ignore the ByteBuffer parameter.

If this is a useful feature, I think that we should update them to use the supplied ByteBuffer if not null. If it isn't a useful feature, we should instead remove the ByteBuffer parameter from the API.
