> Currently Datanode creates chunk files as they are received from HDDS client. 
>  This creates a conflict between requirements: client would like to use less 
> memory for buffering, but datanode needs to avoid small files.
> The goal of this task is to decouple client and server write sizes to allow 
> the client to send data in smaller increments without affecting datanode 
> storage.
