The changes introduced in > HIVE-3976 for DecimalTreeWriter can create null values after updating the > isPresent stream. > https://github.com/apache/hive/blob/branch-0.13/ql/src/java/org/apache/hadoop/hive/ql/io/orc/WriterImpl.java#L1337 > As result of the above return statement, isPresent stream state can become > wrong. The isPresent stream thinks all values are non-null and hence > suppressed. But the data stream will be of 0 length.
