无法写入本地HDFS datanode

我尝试使用java程序将文件写入我的本地HDFS设置,我正在使用Hadoop 2.3.0分发和hadoop-client 2.3.0 hadoop-hdfs 2.3.0库.

在HDFS日志中,它显示以下错误:

2014-04-07 18:40:44,479 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: prabhathp:50010:DataXceiver error processing unknown operation  src: /127.0.0.1:38572 dest: /127.0.0.1:50010

有人可以解释一下吗？
