I can confirm that TEZ is much faster than MR in pretty much all cases. Also, with hive, you'll make sure you've performed optimizations like aligning ORC stripe sizes with HDFS block sizes, and concatenated your tables (not so much an optimization as a must for avoiding the small files problem).

It contains (currently) more optimizations than Hive on Spark. I assume you use the latest Hive version. Additionally you may want to think about calculating statistics (depending on your configuration you need to trigger it) - I am not sure if Spark can use them. I am not sure if bloom filters on the columns you mention make sense. You may also want to increase stride size (depending on your data). Currently you bucket by a lot of fields, which may not make sense. You also may want to sort the data by customer Id in the table. You also seem to have a lot of reducers, which you may want to decrease. Have you tried without "having stddev_samp" ? Is the query exactly the same as in Sybase?
