> Enable HDFS write on streams as an attribute

> Project: Apache Apex Core
> Issue Type: Task
> Reporter: Gavin
> Assignee: Chetan Narsude
> Priority: Critical
>
> On a stream, enable spooling the streams to HDFS. This needs the following to
> be specified
> - Physical partitions: Since partitions are decided via input port, putting
> partitions on stream (written to by output ports) requires special handling
> - Write policy (directory, partitionining to be consumed by consumers, hive?,
> hcatalog, ...)
> - Ability to ask for partitions to be derived from bandwidth. Assume one
> physical HDFS write can only do 30 MB/sec. User should be able to say "derive
> the number of HDFS writers", or "use N writers and grow them if throughput
> goes up"
