NPE in org.apache.spark.sql.hive.HiveShim$.toCatalystDecimal(HiveShim.scala:106)

Still reproducible in Spark 3.0.1.

How to reproduce:

SHELL

> export SPARK_MAJOR_VERSION=3

SPARK PART 1

> spark-shell --master local
SPARK_MAJOR_VERSION is set to 3, using Spark3
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
