[jira] [Created] (HIVE-19723) Arrow serde: "Unsupported data type: Timestamp(NANOSECOND, null)"

---------------------------------

             Summary: Arrow serde: "Unsupported data type: Timestamp(NANOSECOND, null)"
                 Key: HIVE-19723
                 URL: https://issues.apache.org/jira/browse/HIVE-19723
             Project: Hive
          Issue Type: Bug
            Reporter: Teddy Choi
            Assignee: Teddy Choi


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.
