> There is work that's in progress to implement the storage based on a Phoenix 
> schema (YARN-3134).
> In parallel, we would like to explore an implementation based on a native 
> HBase schema for the write path. Such a schema does not exclude using 
> Phoenix, especially for reads and offline queries.
> Once we have basic implementations of both options, we could evaluate them in 
> terms of performance, scalability, usability, etc. and make a call.
