Thanks [~leftnoteasy] for the comments.
bq.When RM is runs on the local host, we still need to run corsproxy. Do you
know what can we do to fix it?
I have enabled cors-proxy headers in RM as per YARN-4009. With this support, I
can launch and view new YARN web ui w/o corsproxy.

bq.And if you have some bandwidth, could you test the patch on a distributed
environment?
I have tested this in 5-node cluster. Seems fine.
