Li Lu commented on YARN-3411:
-----------------------------

Hi [~djp]! I totally agree with your concerns. However, for now the Phoenix 
storage system still doesn't have the support to timeline series data. This 
said, maybe we can firstly focus on the storage of "single data", and then 
address the problems for timeline series in a separate JIRA? I'd appreciate 
your suggestions on this. Thanks!

> 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.
