Subru Krishnan commented on YARN-5597:
--------------------------------------
[~bibinchundatt], we use a RDBMS (SQL) for the Federation store and ZK for RM
store as 1) there's no leader election in Federation and 2) We only store
metadata for which a DB performs great and not what ZK is intended for (IMHO Zk
has abused/misused a lot).
That said, [~elgoiri] has a deployment with ZK for both Federation and RM
stores, so he should be able to guide you.
