Description

Running TPCH SF100 Parquet (and CSV) tests, multiple queries failed due to OOM. For example, Q16 hit the following error:

java.sql.SQLException: RESOURCE ERROR: One or more nodes ran out of memory while executing the query.

Unable to allocate sv2 for 65536 records, and not enough batchGroups to spill.
batchGroups.size 1
spilledBatchGroups.size 0
allocated memory 23500416
allocator limit 20000000
Fragment 1:11
