Aaron T. Myers commented on HDFS-3153:
--------------------------------------
Thanks a lot for the link, Nicholas.
My trouble with this proposal is that I don't understand how this meaningfully
improves things. The motivation described in that comment you linked to seems
to be:
# Continue to support client-side configuration of HA addresses.
# Support IP failover.
# Support putting this configuration in some central service like ZK or DNS.
# Start referring to "nameservices" as "volumes" in the configs.
The current configuration system definitely supports #1, and it's not obvious
to me that the current configuration system can't support #2 and #3. As for #4,
since there's currently a 1-to-1 mapping between volume and nameservice, it
seems like the current system is sufficient there as well.
Am I perhaps misunderstanding the motivation for the change?
