-----------------------------------------------------------------
Thanks, [~attilapiros]. I also confirmed that this bug exists in 2.0.2/1.6.3 while `date_format` works correctly.
{code}
scala> sql("select dayOfYear('1500-01-01')").show
+-----------------------------------+
|dayofyear(CAST(1500-01-01 AS DATE))|
+-----------------------------------+
| 10|
+-----------------------------------+
scala> sc.version
res2: String = 2.0.2
{code}
{code}
scala> sql("select date_format('1500-01-01', 'D')").show
+---------------------------------------------+
|date_format(CAST(1500-01-01 AS TIMESTAMP), D)|
+---------------------------------------------+
| 1|
