Subject [jira] [Commented] (YARN-3411) [Storage implementation] explore the native HBase write schema for storage

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

Hi [~vrushalic] [~zjshen], just a quick thing to confirm that we want to use byte arrays for
config and info fields in both of our storage. I'll convert the type for config and info in
the Phoenix implementation to VARBINARY to be consistent with this design.

> 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.
