集群中五台datanode结果只起来四台,查看没起来的那台datanode日志,发现报错如下:

org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.protocol.UnregisteredNodeException): Data node DatanodeRegistration(192.168.1.204:50010, datanodeUuid=809917ff-7b27-47d6-970e-76418779c9ec, infoPort=50075, infoSecurePort=0, ipcPort=50020, storageInfo=lv=-56;cid=CID-36266625-9883-4184-bd9a-309f3cbd60f2;nsid=2035073548;c=0) is attempting to report storage ID 809917ff-7b27-47d6-970e-76418779c9ec.

猜测是storage id出错了,应该是我备份镜像的时候,没删掉这个data。

于是找到datanode的data文件价,移去current文件夹,重新启动datanode:

hadoop-daemon.sh start datanode

正常启动了
