Description

The major reason is because in the YARN unit tests, it is not using the address that the RM is binded to, but rather using the one in yarn-default.xml

It fails with error like this:

java.lang.RuntimeException: java.net.UnknownHostException: Invalid host name: local host is: (unknown); destination host is: "testing-worker-linux-10-1-15919-linux-11-30791059":8032; java.net.UnknownHostException; For more details see: http://wiki.apache.org/hadoop/UnknownHost
