Ashutosh Chauhan updated HIVE-3168: ----------------------------------- Resolution: Fixed Fix Version/s: (was: 0.9.1) Status: Resolved (was: Patch Available) Committed. Thanks, Thejas! > LazyBinaryObjectInspector.getPrimitiveJavaObject copies beyond length of > underlying BytesWritable > ------------------------------------------------------------------------------------------------- > > Key: HIVE-3168 > URL: https://issues.apache.org/jira/browse/HIVE-3168 > Project: Hive > Issue Type: Bug > Components: Serializers/Deserializers > Affects Versions: 0.9.0 > Reporter: Thejas M Nair > Assignee: Thejas M Nair > Fix For: 0.10.0 > > Attachments: HIVE-3168.1.patch, HIVE-3168.2.patch, HIVE-3168.3.patch > > > LazyBinaryObjectInspector.getPrimitiveJavaObject copies the full capacity of > the LazyBinary's underlying BytesWritable object, which can be greater than > the size of the actual contents. > This leads to additional characters at the end of the ByteArrayRef returned. > When the LazyBinary object gets re-used, there can be remnants of the later > portion of previous entry. > This was not seen while reading through hive queries, which I think is > because a copy elsewhere seems to create LazyBinary with length == capacity. > (probably LazyBinary copy constructor). This was seen when MR or pig used > Hcatalog to read the data. -- This message is automatically generated by JIRA.
