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.WebAppP=
roxyServlet: dr.who is accessing unchecked http://computer85:46254 which is=

p://computer85:8088 refused
Looking over the Internet I've found several versions of this problems, som=
e of them configuration, some of them old bugs. I added the following prope=
rty 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

<br>
checking the logs in the master I have only found this warning:<br>
<br>
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<br> 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<br> <br>
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:<br> <br>
<property><br>
<description>The address of the RM web \
application.</description><br> \
<name>yarn.resourcemanager.webapp.address</name><br> \
<value>${yarn.resourcemanager.hostname}:8088</value><br> \
</property><br> <br>
Do you know what I'm missing to have this problem?<br>
<br>
I have setted up 4 clusters of Hadoop... but this one is being a nightmare. <br>
<br>
Thank<br>
