Exception in thread "main" java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.RetriableException): org.apache.hadoop.hdfs.server.namenode.SafeModeException:

The reported blocks 9 needs additional 7 blocks to reach the threshold 0.9990 of total blocks 16. The number of live datanodes 3 has reached the minimum number 0. Safe mode will be turned off automatically once the thresholds have been reached.
关闭namenode节点的安全模式即可:
[hadoopdjt11 bin]$ hadoop dfsadmin -safemode leave
