Navis commented on HIVE-5342:
-----------------------------
Removing counter in Operator is the first step. There would be following works
related to this, something like,
1. replace serde2.io.*Writable with hadoop.io.*Writable
2. remove shims for comparing Text
3. possibly removing ByteArrayRef in Lazy<Non-Primitives>
4. etc.
I'll check the HIVE-4518, but it seemed a little intrusive at first look.
> Remove pre hadoop-0.20.0 related codes
