> hadoop-2.7.0/src/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/client/RMProxy.java
> {code}

> into the configuration.

> final Class<T> protocol, RMProxy instance) throws IOException {
> YarnConfiguration conf = (configuration instanceof YarnConfiguration)
