Eli Collins commented on HADOOP-8210:
-------------------------------------
HDFS-3148, which this jira tracks the common side of, just pertains to outgoing
client interfaces, so doesn't pertain to datanode IPs. However, I think your
comment is relevant to HADOOP-8198. I think HADOOP-7510 is complimentary, if we
don't use hostnames then we'd have to have a separate service token for each
interface on the datanode. Could you take a look at the design doc and see if
it jives with what you're thinking?
