Srinivasa Reddy Vundela updated SPARK-11484:
--------------------------------------------
    Description: 
Customer reported a strange UI when running spark application through Oozie in 
Uber mode (Issue was observed only in yarn-client mode).

When debugging the sparkUI through chrome developer console, figured out that 
CSS files are looked for in different applicationId (Oozie mapreduce 
application) instead of actual spark application. (Please see the attached 
screenshot for more information).

Looking into the live sparkUI code, it seems that proxyBase is taken from 
APPLICATION_WEB_PROXY_BASE instead of spark property spark.ui.proxyBase 
(Pointing to the actual spark application). This issue might be reproducible if 
the above specified env is set manually or set by other job. 

Fix would be giving precedence to spark property (which might be correct in 
most cases when it was set).
