Can't the partition path be used as the key?
> storm-hdfs should support writing to multiple files
> ---------------------------------------------------
>
> Key: STORM-1464
> URL: https://issues.apache.org/jira/browse/STORM-1464
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-hdfs
> Reporter: Aaron Dossett
> Assignee: Aaron Dossett
> Labels: avro
>
> Examples of when this is needed include:
> - One avro bolt writing multiple schemas, each of which require a different
> file. Schema evolution is a common use of avro and the avro bolt should
> support that seamlessly.
> - Partitioning output to different directories based on the tuple contents.
> For example, if the tuple contains a "USER" field, it should be possible to
> partition based on that value.
