Hi, all:
I run spark on yarn,  I want to see the Jobs UI http://ip:4040/,
but it redirect to http://${yarn.ip}/proxy/application_1428110196022_924324/ 
which can not be found. Why?
Anyone can help?

whenever you point your browser directly at the web UI of a YARn app, it 
redirects you the YARN resource manager, which acts as a proxy (the way you see 
it as you go through the YARN resource manager web)

it looks like here the configuration yarn-site.xml used when you launched the 
application isn't right, the URL to the rmproxy is being configured from 
another property there, yarn.ip, which isn't defined.

have a look at the yarn.resourcemanager.address value

    <property>
      <name>yarn.resourcemanager.address</name>
      
<value>myresourcemanager.example.org<http://myresourcemanager.example.org>:8050</value>
    </property>
