当我试图调用一个远程方法时有一个例外，

2013-01-28 16:46:09,911 ERROR org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:training (auth:SIMPLE) cause:org.apache.hadoop.ipc.RPC$VersionMismatch: Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch. (client = 69, server = 1)
2013-01-28 16:46:09,912 INFO org.apache.hadoop.ipc.Server: IPC Server handler 1 on 8020, call org.apache.hadoop.hdfs.protocol.ClientProtocol.getFileInfo from 192.168.140.1:55126: error: org.apache.hadoop.ipc.RPC$VersionMismatch: Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch. (client = 69, server = 1)
org.apache.hadoop.ipc.RPC$VersionMismatch: Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch. (client = 69, server = 1)

我正在使用cloudera cdh4 vm（版本2.0.0-mr1-cdh4.1.2）
服务器端的clientprotocol怎么会有“1”的版本？

hadoop rpc
