在使用以下配置的apachenifi1.2.1上的puthdfs处理器时；
hadoop configuration reource : /usr/local/hadoop-2.7.0/etc/hadoop/core-site.xml, /usr/local/hadoop-2.7.0/etc/hadoop/hdfs-site.xml
directory: /mydir我面对下面的错误。
Caused by: org.apache.hadoop.ipc.RemoteException: File /tweets/.381623121831518.json could only be replicated to 0 nodes instead of minReplication (=1). There are 0 datanode(s) running and no node(s) are excluded in this operation.

我按照以下程序来纠正这个问题；
停止所有服务
删除hdfs-site.xml中提到的namenode和datanode目录
设置名称节点格式
启动所有hadoop服务
验证：
检查所有正在运行的服务
检查在puthdfs processor->destination directory中指定的/mydir中传输的文件。此目录中应该有传输的文件
