Sangjin Lee commented on YARN-3699:
-----------------------------------

Thanks [~djp] for your comments!

Once everyone's comfortable with the decision of not making the flow version 
part of the row key, then we could resolve this JIRA by recording that decision 
(+1 or -1). Then we could open a separate JIRA for the phoenix writer to 
relocate the flow version (remove it from the PK). But a bigger question there 
is, if we're going with the native HBase schema, what is the status of the 
phoenix writer implementation?

For me, (if it wasn't obvious in previous comments), I'm +1 with the flow 
version *not* being in the row key.
