> I had a hadoop.http.filter.initializers in place to do user authentication,
> but was purposely trying to let it bypass authentication on certain pages.
> One of those was the proxy and the application master main page. When I then
> tried to go to the application master through the proxy it throws an internal
> server error:
> Problem accessing /mapreduce. Reason:
> INTERNAL_SERVER_ERROR
> Caused by:
> java.lang.NullPointerException
> at
> org.apache.hadoop.yarn.server.webproxy.amfilter.AmIpFilter.doFilter(AmIpFilter.java:100)

> org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1212)

> org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1212)
> It looks like the problem is that AmIpFilter doesn't check for null returned
> from httpReq.getCookies()
