----------------------------------
Thanks a lot, Thejas. It is working fine now.

> 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, 0.9.1
>

>
> 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.
