## What changes were proposed in this pull request? ORC 1.4.4 includes [nine fixes](https://issues.apache.org/jira/issues/?filter=12342568&jql=project%20%3D%20ORC%20AND%20resolution%20%3D%20Fixed%20AND%20fixVersion%20%3D%201.4.4). One of the issues is about `Timestamp` bug (ORC-306) which occurs when `native` ORC vectorized reader reads ORC column vector's sub-vector `times` and `nanos`. ORC-306 fixes this according to the [original definition](https://github.com/apache/hive/blob/master/storage-api/src/java/org/apache/hadoop/hive/ql/exec/vector/TimestampColumnVector.java#L45-L46) and this PR includes the updated interpretation on ORC column vectors. Note that `hive` ORC reader and ORC MR reader is not affected. ```scala scala> spark.version res0: String = 2.3.0 scala> spark.sql("set spark.sql.orc.impl=native") scala> Seq(java.sql.Timestamp.valueOf("1900-05-05 12:34:56.000789")).toDF().write.orc("/tmp/orc") scala> spark.read.orc("/tmp/orc").show(false) +--------------------------+ |value | +--------------------------+ |1900-05-05 12:34:55.000789| +--------------------------+ ``` This PR aims to update Apache Spark to use it. **FULL LIST** ID | TITLE -- | -- ORC-281 | Fix compiler warnings from clang 5.0 ORC-301 | `extractFileTail` should open a file in `try` statement ORC-304 | Fix TestRecordReaderImpl to not fail with new storage-api ORC-306 | Fix incorrect workaround for bug in java.sql.Timestamp ORC-324 | Add support for ARM and PPC arch ORC-330 | Remove unnecessary Hive artifacts from root pom ORC-332 | Add syntax version to orc_proto.proto ORC-336 | Remove avro and parquet dependency management entries ORC-360 | Implement error checking on subtype fields in Java ## How was this patch tested?
