> make maximum RPC buffer size configurable
> -----------------------------------------
>
> Key: HADOOP-9676
> URL: https://issues.apache.org/jira/browse/HADOOP-9676
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 2.1.0-beta
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Priority: Minor
> Attachments: HADOOP-9676.001.patch, HADOOP-9676.003.patch
>
>
> Currently the RPC server just allocates however much memory the client asks
> for, without validating. It would be nice to make the maximum RPC buffer
> size configurable. This would prevent a rogue client from bringing down the
> NameNode (or other Hadoop daemon) with a few requests for 2 GB buffers. It
> would also make it easier to debug issues with super-large RPCs or malformed
> headers, since OOMs can be difficult for developers to reproduce.
