Subject question about yarn to tez webUI redirect
Date Tue, 27 Sep 2016 18:16:04 GMT
Hi,

In our set up, the Tez UI is hosted under a subfolder "tez-ui" in tomcat,
e.g. http://tez.com:50060/tez-ui/. Somehow after the job has completed, the
redirect Tez URI from yarn UI has redundant "tez-ui" in it, thus doesn't
work.

The tracking url Tez sends to RM:
http://tez.com:50060/tez-ui/#/tez-app/application_1474998344010_0005
The yarn proxy url:
http://rm.com:50030/proxy/application_1474998344010_0005/tez-ui/#/tez-app/application_1474998344010_0005
The redirected-to tez url when someone clicks on the the yarn proxy url:
http://tez.com:50060/tez-ui/tez-ui/#/tez-app/application_1474998344010_0005
.

That is due to how yarn WebAppProxyServlet reconstructs the The
redirected-to tez url based on the tracking url and the yarn proxy url.

Has anyone run into this?

Thanks.

Ming
