Junping Du commented on YARN-3411:
----------------------------------
bq. While I was discussing the patches with Joep Rottinghuis, we thought it
might be better to call it something more generic so that going forward if we
need to add more columns in other column families, we can reuse some of this
structure.
Ok. I didn't aware of this discussion before. We can leave a TODO later either
to make it more generic or sounds more precisely.
About toLowerCase() which is a pretty trivial comment, feel free to address it
or not.

> 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.
