Cannot connect to Namenode UI

Hi,

HDP 2.2.0

I have a namenode that is not accepting connections on port 50070, although it is actually listening on that port.

015-04-28 13:01:07,162 INFO http.HttpServer2 (HttpServer2.java:openListeners(887)) - Jetty bound to port 50070

tcp 0 0 192.168.105.190:50070 0.0.0.0:* LISTEN 19059/java

cat < /dev/tcp/127.0.0.1/50070 -bash: connect: Connection refused

I do see this in the logs, but I’m not sure it’s related:


2015-04-28 13:01:19,594 WARN resources.ExceptionHandler (ExceptionHandler.java:toResponse(112)) - INTERNAL_SERVER_ERROR
java.lang.NullPointerException

Thanks,

James
