Vinayak Joshi commented on SPARK-16808:
---------------------------------------
The same issue also affects the case where "spark.ui.proxyBase" is set and it
does not get honored in HistoryServer 2.0.
This is a regression in 2.0 from 1.6.
In 2.0, the refactoring of HistoryPage.scala changed the History application
listing to occur from an ajax call. The page listing is rendered using
ui/static/historypage-template.html which does not take into account the
"spark.ui.proxyBase" / APPLICATION_WEB_PROXYBASE when generating the links to
the applications.
The existing History Server test suite
-spark/deploy/history/HistoryServerSuite.scala has an explicit test case to
validate this scenario: "relative links are prefixed with uiRoot
(spark.ui.proxyBase)" - but this test case is broken too because the html it's
receiving and validating no longer contains any application links (as noted
earlier, they are now generated through a js ajax call etc which does not
happen in this test) - so even though the test case passes, it's failing it's
purpose.
> History Server main page does not honor APPLICATION_WEB_PROXY_BASE

> Key: SPARK-16808

> Project: Spark
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Michael Gummelt
>
> The root of the history server is rendered dynamically with javascript, and
> this doesn't honor APPLICATION_WEB_PROXY_BASE:
> https://github.com/apache/spark/blob/master/core/src/main/resources/org/apache/spark/ui/static/historypage-template.html#L67
> Other links in the history server do honor it:
> https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/ui/UIUtils.scala#L146
> This means the links on the history server root page are broken when deployed
> behind a proxy.
