Description

The paging links within the Spark (Yarn) UI are not created as fully qualified URLs. They are only created as stubs:

<a href="/?page=1&amp;showIncomplete=false">&lt; </a><a href="/?page=1&amp;showIncomplete=false">1</a>

This causes problems when Spark Yarn UI is used with Knox. Knox is unable to properly rewrite the URLs because they do not contain the http://**:**/ portion of the URL.

Please make is so that Spark Yarn UI creates fully qualified URLs so that it will page properly when used with Knox.

This is also the case for the link created for "Show incomplete Applications" and the href associated with the spark-logo at the top left.
