Bikas Saha commented on YARN-128:
---------------------------------
Devaraj, I think the current approach+code based on zkstore (that
YARN-128.patch builds on top of) has some significant issues wrt
perf/scalability of ZK/future HA. The design outline attached to this jira
calls out some of the issues. The next proposal document will help clarify a
bit more I hope.
