NameNode not running, port conflict

Replies: 6

Hi there !

I finished earlier my installation of HDP with Ambari, i’m running Ambari 1.4.2 and the installation was fine. But some services didn’t start during the wizard. Especially the HDFS (namenode not running). So i used the dashboard to start it manually but it failed again.
In the logs of the NN, i found this line :

2013-12-23 17:44:09,784 INFO http.HttpServer (HttpServer.java:start(690)) – HttpServer.start() threw a non Bind IOException
java.net.BindException: Port in use: <host>:50070

I thought of a classic problem, but a netstat command was telling me that nothing is using :50070

I try to change the port with the configs pannel of the dashboard, to use 50071. Again, the same problem with a port already in use.

Do you guys have any idea to solve this problem ?

Thanks =)
