Hello, I recently upgraded from Spark 1.6 to Spark 2.0 with Hadoop 2.7. I have some Scala code which I updated for Spark 2.0 that creates parquet tables from textfiles and runs tpc-h queries with the spark.sql module on a 1TB dataset. Most of the queries run as expected with correct results but there are a few like tpc-h query 5 and 7 that return an empty result (in contrast to Spark 1.6). Tables seem to be correctly populated as other queries are executed without problems. What could possibly be the problem?
