flume将数据分流到hdfs报错

在做flume分流到hdfs时，屏幕一直循环报错，各种错误满天飞，最终冷静下来发现了错误的根源是来自以下是信息

java.net.ConnectException:
Call From hadoop002/192.168.112.101 to hadoop001:9000 failed on connection exception:
java.net.ConnectException:
Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

java.net.ConnectException: Connection refused

把配置文件翻看了好久，终于想到是hadoop的rpc通信端口有误，造成了连接异常和被拒，端口改正后，
终于可以正常使用了！！！ ^_^
