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()
