Yossi Ittach commented on HADOOP-3988:
--------------------------------------
We are trying to do something similar - but instead of changing the DNS scheme
, we're using floating IP - So it should override all the caching. I'll update
when I have more results.
> The elephant should remember names, not numbers.

> Issue Type: Bug
> Components: dfs
> Affects Versions: 0.17.2

> The name node and the data node should not cache the resolution of host
> names, as doing so prevents the use of DNS CNAMEs for any sort of fail over
> capability.
