[jira] [Created] (HIVE-3246) java primitive type for binary
datatype should be byte[]
Thejas M Nair created HIVE-3246:
-----------------------------------
Summary: java primitive type for binary datatype should be byte[]
Key: HIVE-3246
URL: https://issues.apache.org/jira/browse/HIVE-3246
Project: Hive
Issue Type: Bug
Affects Versions: 0.9.0
Reporter: Thejas M Nair
Assignee: Thejas M Nair
PrimitiveObjectInspector.getPrimitiveJavaObject is supposed to return a java object. But in case of binary datatype, it returns ByteArrayRef (not java standard type). The suitable java object for it would be byte[].

byte [] is not a primitive. I have no issue with the change but there must be a reason this was done. Likely a performance issue.

bq. byte [] is not a primitive. I have no issue with the change but there must be a reason this was done. Likely a performance issue.
Yes, byte[] is not a java primitive type, but it as close as it gets to it (it is a basic type that ships with java). ByteArrayRef is just a wrapper around byte[], I don't see any performance advantage of using it when binary is converted to java primitive type using the getPrimitiveJavaObject call. Fyi, Ashutosh implemented the binary type using ByteArrayRef in HIVE-2380, I believe he does not see a performance issue as well (based on his comment above.)

I patched v2 of this patch into a clean trunk and was able to run the query that failed in HIVE-3266. It was a simple "select *" from a table using ThriftDeserializer that has a binary field.

Ashutosh Chauhan updated HIVE-3246:
-----------------------------------
Resolution: Fixed
Fix Version/s: 0.10.0
Release Note: This fix changes the internal representation of binary type within Hive. UDFs which were using binary type and making use of the fact that java representation of binary data in Hive is ByteArrayRef needs to be updated to reflect that now that representation is byte[] instead. Also note that this doesn't change the format for on-disk data. (was: Makes the java primitive type for binary datatype - byte[]
)
Hadoop Flags: Incompatible change
Status: Resolved (was: Patch Available)
Committed to trunk. Thanks, Thejas!

Thejas M Nair commented on HIVE-3246:
-------------------------------------
The fix to use byte[] will not be backward compatible, but for the long term I think it is important to fix this. Hopefully, this won't affect too many people as binary datatype is relatively new.

---------------------------------------
We have to do a release note it people who write binary UDFs are going to be effected by the change.
https://github.com/edwardcapriolo/hive_cassandra_udfs
It seems like if you wrote a UDF that returns binary you may be effected depending on how you wrote it.
