Konstantin Shvachko commented on HDFS-6469:
-------------------------------------------
Sanjay, we have been back and forth around the same issues here. So the
question now is whether your last comment is an objection, and if it is, then
to what:
- To creating a single branch rather than two?
- To creating any branches at all?
- To introducing ConsensusNode?
- Or active-active HA approach altogether?
I mean most of this was discussed at the meetup you attended over the phone,
and the decision was made to move forward with developing on branch. Was it not?
Todd, thank you for clarifying on recommended settings. This was not a typical
setup.
