YARN application submit requests have non-knox host:port information

The application submit request via the writable REST api has section like :

am-container-spec": {
"local-resources": {
"entry": {
"key": "AppMaster.jar",
"value":

{ "resource": "hdfs://localhost:9000/user/guest/AppMaster.jar", "type": "FILE", "visibility": "APPLICATION", "size": "41601", "timestamp": "1405544667528" }

}
}
and

"environment": {
"entry": [

{ "key": "DISTRIBUTEDSHELLSCRIPTTIMESTAMP", "value": "1405545208994" }

,
{
"key": "CLASSPATH",
"value": "CLASSPATH<CPS>./<CPS>HADOOP_CONF_DIR<CPS>HADOOP_COMMON_HOME/share/hadoop/common/<CPS>HADOOP_COMMON_HOME/share/hadoop/common/lib/<CPS>HADOOP_HDFS_HOME/share/hadoop/hdfs/<CPS>HADOOP_HDFS_HOME/share/hadoop/hdfs/lib/<CPS>HADOOP_YARN_HOME/share/hadoop/yarn/<CPS>HADOOP_YARN_HOME/share/hadoop/yarn/lib/*<CPS>./log4j.properties"
},

{ "key": "DISTRIBUTEDSHELLSCRIPTLEN", "value": "50" }

,

{ "key": "DISTRIBUTEDSHELLSCRIPTLOCATION", "value": "hdfs://localhost:9000/user/guest/shellCommands.sh" }

]
}

The host and port info needs to be something that gets filled out by Knox.
