Subject Click in Application manager gives Error 500
Date Thu, 25 Feb 2016 16:33:47 GMT
When I click in the application manager link in the web GUI I get an error 500 (hadoop 2.7.2):


HTTP ERROR 500

Problem accessing /proxy/application_1456416539194_0001/. Reason:

    Connection to http://computer85:8088 refused

checking the logs in the master I have only found this warning:

2016-02-25 17:20:32,093 INFO org.apache.hadoop.yarn.server.webproxy.WebAppProxyServlet: dr.who
is accessing unchecked http://computer85:46254 which is the app master GUI of application_1456416539194_0001
owned by rgonzalez
2016-02-25 17:20:32,105 WARN org.mortbay.log: /proxy/application_1456416539194_0001/: org.apache.http.conn.HttpHostConnectException:
Connection to http://computer85:8088 refused

Looking over the Internet I've found several versions of this problems, some of them configuration,
some of them old bugs. I added the following property to the yarn-site.xml but still is not
working:

<property>
  <description>The address of the RM web application.</description>
   <name>yarn.resourcemanager.webapp.address</name>
   <value>${yarn.resourcemanager.hostname}:8088</value>
</property>

Do you know what I'm missing to have this problem?

I have setted up 4 clusters of Hadoop... but this one is being a nightmare.

Thank
Roberto
