Todd Lipcon commented on HDFS-1623:
-----------------------------------
bq. From experience, I suspect getting the code for IP based automated failover
working in a multi-SBN approach to where the community is ready to see it as a
stable codebase/release will probably take some more investment.
yep, I didn't mean to indicate that the whole project is trivial. Just that the
majority of issues we had to solve for the current failover implementation also
apply to the IP-failover implementation. The remaining work to do IP-failover
is much smaller than the amount already behind us.
