> Spark's Arrow support only provides Timestamp at MICROSECOND granularity. Spark 2.3.0 won't accept NANOSECOND. Switch it back to MICROSECOND.
> The unit test org.apache.hive.jdbc.TestJdbcWithMiniLlapArrow will just need to change the assertion to test microsecond. And we'll need to add this to documentation on supported datatypes.
