Ashutosh Chauhan commented on HIVE-4961:
----------------------------------------
hcatalog tests are flaky and we can ignore them. But, none of hive tests fail
in trunk. Its not likely related to your patch though. I have seen {{input4.q}}
and {{plan_json.q}} to fail consistently only on vectorization branch, so they
need to be debugged on branch. orc tests I am not sure, but if they fail
regardless of patch, I think this patch is good to go.
> Create bridge for custom UDFs to operate in vectorized mode

> Suppose you have a custom UDF myUDF() that you've created to extend hive. The
> goal of this JIRA is to create a facility where if you run a query that uses
> myUDF() in an expression, the query will run in vectorized mode.
> This would be a general-purpose bridge for custom UDFs that users add to
> Hive. It would work with existing UDFs.
> I'm considering a separate JIRA for a new kind of custom UDF implementation
> that is vectorized from the beginning, to optimize performance. That is not
> covered by this JIRA.
