Attachment: HIVE-6952_branch-13.patch
patch for branch 0.13
> Hive 0.13 HiveOutputFormat breaks backwards compatibility
> ---------------------------------------------------------
>
> Key: HIVE-6952
> URL: https://issues.apache.org/jira/browse/HIVE-6952
> Project: Hive
> Issue Type: Bug
> Components: File Formats, Serializers/Deserializers
> Affects Versions: 0.13.0
> Reporter: Costin Leau
> Assignee: Ashutosh Chauhan
> Priority: Blocker
> Fix For: 0.14.0
>
> Attachments: HIVE-6952.patch, HIVE-6952_branch-13.patch
>
>
> Hive 0.13 changed the signature of HiveOutputFormat (through commit r1527149)
> breaking backwards compatibility with previous releases; the return type of
> getHiveRecordWriter has been changed from RecordWriter to FSRecordWriter.
> FSRecordWriter introduces one new method on top of RecordWriter however it
> does not extend the previous interface and it lives in a completely new
> package.
> Thus code running fine on Hive 0.12 breaks on Hive 0.13. After the upgrade,
> code running on HIve 0.13, will break on anything lower than this.
> This could have easily been avoided by extending the existing interface or
> introducing a new one that RecordWriter could have extended going forward. By
> changing the signature, the existing contract (and compatibility) has been
> voided.
