> "The Writables are originally from org.apache.hadoop.io. I tend to assume that they have been re-defined in hive if the original implementation was not considered good enough.
> However, I don't understand why some are defined twice in hive itself. I noticed that ByteWritable in o.a.h.hive.ql.exec is not being used anywhere. The ByteWritable in serde2.io is being referred to in bunch of places. Therefore, I would suggest to just use the one in serde2.io."
