Description:
Repro:
{{val path = "/tmp/someparquetfile"}}
{{spark.sql("SELECT CAST('2019-01-01 00:00:00' AS TIMESTAMP_NTZ) AS
field").write.mode("overwrite").parquet(path)}}
{{spark.read.schema("field array<timestamp_ntz>").parquet(path).collect()}}
Depending on the memory mode, it will throw an NPE on OnHeap mode and SEGFAULT
on OffHeap mode.
