Neha Tomar commented on HIVE-3168:
----------------------------------
Thanks Thejas. I applied only the second patch and the build was fine. However,
I am still seeing the same incorrect values coming back. Could you please let
me know if you have verified and this works fine for you.
e.g. I have following data in table.
a
ab
abc
abcd
abcde
z
And the values (this is in hexadecimal) coming back from HCatalog is :
61
616200
616263
616263640000
616263646500
7A6263646500

> 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
>
> Attachments: HIVE-3168.1.patch, HIVE-3168.2.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.
