> h6. Usecase
> Client sits outside of the YARN subnet. YARN/TEZ passes out internal host addresses which are not resolvable by the client. Example: test-environment where YARN sits in ec2 and the test/client sits outside.
> h6. Solution
> Use NetUtils.createSocketAddrForHost() instead of new InetSocketAddress() in TezClientUtils#getAMProxy().
> This would allow to use NetUtils.addStaticResolution() which can be used to have a static private -> public mapping!
