Allen Wittenauer commented on HDFS-2231:
----------------------------------------
bq. To discover NNStandbyAddress clients and datanode may try NNAddress1 and
NNAddress2 or use mechanism such as Zookeeper.
Why? Shouldn't they only care about the VIP in a real HA scenario? What is
the value of the VIP if clients are going to be aware of and try both addresses
anyway?
