--------------------------------
Parth,
Thanks for offering. I have a patch that's almost ready. Will upload soon.
> OffsetCommitRequest API - timestamp field is not versioned
> ----------------------------------------------------------
>
> Key: KAFKA-1841
> URL: https://issues.apache.org/jira/browse/KAFKA-1841
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.8.2
> Environment: wire-protocol
> Reporter: Dana Powers
> Priority: Blocker
> Fix For: 0.8.2
>
>
> Timestamp field was added to the OffsetCommitRequest wire protocol api for
> 0.8.2 by KAFKA-1012 . The 0.8.1.1 server does not support the timestamp
> field, so I think the api version of OffsetCommitRequest should be
> incremented and checked by the 0.8.2 kafka server before attempting to read a
> timestamp from the network buffer in OffsetCommitRequest.readFrom
> (core/src/main/scala/kafka/api/OffsetCommitRequest.scala)
> It looks like a subsequent patch (KAFKA-1462) added another api change to
> support a new constructor w/ params generationId and consumerId, calling that
> version 1, and a pending patch (KAFKA-1634) adds retentionMs as another
> field, while possibly removing timestamp altogether, calling this version 2.
> So the fix here is not straightforward enough for me to submit a patch.
> This could possibly be merged into KAFKA-1634, but opening as a separate
> Issue because I believe the lack of versioning in the current trunk should
> block 0.8.2 release.
