Description

The docs yarn-default.xml miss the default values of the following parameters:
yarn.web-proxy.address
yarn.ipc.client.factory.class
yarn.ipc.server.factory.class
yarn.ipc.record.factory.class

Here we go,

YarnConfiguration.java

  97   /** Factory to create client IPC classes.*/
  98   public static final String IPC_CLIENT_FACTORY_CLASS =
  99     IPC_PREFIX + "client.factory.class";
 100   public static final String DEFAULT_IPC_CLIENT_FACTORY_CLASS =
 101       "org.apache.hadoop.yarn.factories.impl.pb.RpcClientFactoryPBImpl";
 102 
 103   /** Factory to create server IPC classes.*/
 104   public static final String IPC_SERVER_FACTORY_CLASS =
 105     IPC_PREFIX + "server.factory.class";
 106   public static final String DEFAULT_IPC_SERVER_FACTORY_CLASS =
 107       "org.apache.hadoop.yarn.factories.impl.pb.RpcServerFactoryPBImpl";
 108 
 109   /** Factory to create serializeable records.*/
 110   public static final String IPC_RECORD_FACTORY_CLASS =
 111     IPC_PREFIX + "record.factory.class";
 112   public static final String DEFAULT_IPC_RECORD_FACTORY_CLASS =
 113       "org.apache.hadoop.yarn.factories.impl.pb.RecordFactoryPBImpl";
 ...
 1119   /** The address for the web proxy.*/
 1120   public static final String PROXY_ADDRESS =
 1121     PROXY_PREFIX + "address";
 1122   public static final int DEFAULT_PROXY_PORT = 9099;
 1123   public static final String DEFAULT_PROXY_ADDRESS =
 1124     "0.0.0.0:" + DEFAULT_PROXY_PORT;
