> Compress ZK YARN keys to scale up (especially AppStateData
> ----------------------------------------------------------
>
> Key: YARN-6426
> URL: https://issues.apache.org/jira/browse/YARN-6426
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: yarn
> Affects Versions: 3.0.0-alpha2
> Reporter: Roni Burd
> Assignee: Roni Burd
> Labels: patch
> Attachments: zkcompression.patch
>
>
> ZK today stores the protobuf files uncompressed. This is not an issue except
> that if a customer job has thousands of files, AppStateData will store the
> user context as a string with multiple URLs and it is easy to get to 1MB or
> more.
> This can put unnecessary strain on ZK and make the process slow.
> The proposal is to simply compress protobufs before sending them to ZK
