Eric Hanson commented on HIVE-4961:
-----------------------------------
I ran the failing tests on my machine on a clean version of the vectorization
branch without my patch. These tests failed:
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_input4
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_plan_json
org.apache.hadoop.hive.ql.io.orc.TestFileDump.testDictionaryThreshold
org.apache.hadoop.hive.ql.io.orc.TestFileDump.testDump
These tests would not run in a way that produced output in ant testreport, and
my changes should not affect them.
org.apache.hcatalog.listener.TestNotificationListener.testAMQListener
org.apache.hive.hcatalog.fileformats.TestOrcDynamicPartitioned.testHCatDynamicPartitionedTable
org.apache.hive.hcatalog.fileformats.TestOrcDynamicPartitioned.testHCatDynamicPartitionedTableMultipleTask
org.apache.hive.hcatalog.pig.TestHCatStorer.testPartColsInData
org.apache.hive.hcatalog.pig.TestHCatStorer.testStoreInPartiitonedTbl
org.apache.hive.hcatalog.pig.TestHCatStorer.testStoreMultiTables

> 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.
