Aaron T. Myers commented on HDFS-3200:
--------------------------------------

Patch looks pretty good to me, Todd. One small comment. +1 once this is addressed:

# s/namespace/nameservice/g in "to be overridden on a per-namespace or per-namenode basis."

> Currently the ZKFC is configured with a global set of configs. But different nameservices
may want to use different ZooKeeper quorums, ACLs, znodes, etc. So, we should optionally allow
the confs to be specified with a nameservice suffix, overriding the same config with no suffix.
