> Hello,
> I am facing a similar issue as described in SPARK-5837, but is my case the 
> SparkUI only work in "yarn-client" mode. If a run the same job using 
> "yarn-cluster" I get the HTTP 500 error:
> {code}
> HTTP ERROR 500
> Problem accessing /proxy/application_1444297190346_0085/. Reason:
>     Connection to http://XX.XX.XX.XX:55827 refused
> Caused by:
> org.apache.http.conn.HttpHostConnectException: Connection to 
> http://XX.XX.XX.XX:55827 refused
>       at 
> org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:190)

> {code}
> I have verified that the UI port "55827" is actually Listening on the worker 
> node, I can even run a "curl http://XX.XX.XX.XX:55827"; and it redirects me to 
> another URL: http://YY.YY.YY.YY:8088/proxy/application_1444297190346_0082
> The strange thing is the its redirecting me to the app "_0082" and not the 
> actually running job "_0085"
> Does anyone have any suggestions on what could be causing this issue?
