> HIVE-3976 can cause ORC file to be unreadable. 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. When reading such files we will get the following exception
> {code}
> Caused by: java.io.EOFException: Reading BigInteger past EOF from compressed stream Stream
for column 3 kind DATA position: 0 length: 0 range: 0 offset: 0 limit: 0
