internal server error trying access application master via proxy with filter enabled ------------------------------------------------------------------------------------
Key: MAPREDUCE-3702 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3702 Project: Hadoop Map/Reduce Issue Type: Bug Components: mrv2 Affects Versions: 0.23.0 Reporter: Thomas Graves Assignee: Thomas Graves Priority: Critical 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) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1212) at org.apache.hadoop.http.HttpServer$QuotingInputFilter.doFilter(HttpServer.java:940) at 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() -- This message is automatically generated by JIRA.
