Sean Busbey updated HIVE-3585:
------------------------------
Attachment: HIVE-3585.2.patch.txt
Updated patch rebased onto trunk. [review
board|https://reviews.apache.org/r/14204/]
Depends on HIVE-5302 being applied to allow testing
* Updated Avro to 1.7.5
* update AvroRecordReaderBase for changes that have since happened in
AvroGenericRecordReader
* added client positive queries that hit MR, per feedback from [~appodictic]
* added .out for avro_parition_format.q
Personally, I think the performance issues can wait for a follow up ticket. esp
once we can use a version of Trevni that has a solution for AVRO-1208 in place.
> Integrate Trevni as another columnar oriented file format
