Weiwei Yang commented on YARN-3601:
-----------------------------------
I set a false flag so that HttpURLConnection does NOT automatically follow the
redirect, this fixes too many redirections problem. (In the past it doesn't
have this problem because there is a refresh time of 3 seconds so the client is
still able to retrieve the redirect url from the http header). I am now able to
retrieve redirection url from header field "Location", and null if there is no
redirection. The overall logic is not changed, the test case is fixed now.
