> TPCDS query 66 degraded by 30% in 1.6.0 compared to 1.4.1

> Key: SPARK-13307
> URL: https://issues.apache.org/jira/browse/SPARK-13307
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.0
> Reporter: JESSE CHEN
>
> Majority of the TPCDS queries ran faster in 1.6.0 than in 1.4.1, average
> about 9% faster. There are a few degraded, and one that is definitely not
> within error margin is query 66.
> Query 66 in 1.4.1: 699 seconds
> Query 66 in 1.6.0: 918 seconds
> 30% worse.
> Collected the physical plans from both versions - drastic difference maybe
> partially from using Tungsten in 1.6, but anything else at play here?
> Please see plans here:
