Jason Dere created HIVE-7041:
--------------------------------
Summary: DoubleWritable/ByteWritable should extend their hadoop
counterparts
Key: HIVE-7041
URL: https://issues.apache.org/jira/browse/HIVE-7041
Project: Hive
Issue Type: Bug
Reporter: Jason Dere
Assignee: Jason Dere
Attachments: HIVE-7041.1.patch
Hive has its own implementations of ByteWritable/DoubleWritable/ShortWritable.
We cannot replace usage of these classes since they will break 3rd party
UDFs/SerDes, however we can at least extend from the Hadoop version of these
classes when possible to avoid duplicate code.
When Hive finally moves to version 1.0 we might want to consider removing use
of these Hive-specific writables and switching over to using the Hadoop version
of these classes.
ShortWritable didn't exist in Hadoop until 2.x so it looks like we can't do it
with this class until 0.20/1.x support is dropped from Hive.
