Description

SELECT LEAST(1, 1.5);

Error: org.apache.spark.sql.AnalysisException: cannot resolve 'least(1, CAST(2.1 AS DECIMAL(2,1)))' due to data type mismatch: The expressions should all have the same type, got LEAST (ArrayBuffer(IntegerType, DecimalType(2,1))).; line 1 pos 7 (state=,code=0)

This query works for 1.6.
