Daniel Dai commented on PIG-3294:
---------------------------------
bq. The checking in of Hive code is ugly. We need to make sure that gets
removed before a release so we don't end up forking.
Sure, the duplication is ugly. I already commented on the code "Will remove
once we switch to use Hive 1.2.0". I expect to remove those classes in the next
release. However, in this release, I don't want to create a dependency on Hive
1.2.0. That will complicate the release process. Those classes are simple
enough and don't likely to cause trouble for a short while.
bq. In POForEach you are visiting the physical plan at run time to determine if
we need the last record
Yes, I can cache the flag and not do this in the backend. Will update patch
shortly.
bq. HiveUtils.java: much of this code to convert Hive types to Pig types must
already be in HCat. Is it not possible to re-use that?
Sure, we can consolidate these code. Since Pig don't depend on HCat, but HCat
depends on Pig, I guess we shall rework HCat to use the same code to do the
type conversion.

> It would be nice if Pig provide some interoperability with Hive. We can wrap
> Hive UDF in Pig so we can use Hive UDF in Pig.
