Exception in thread "main" java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.SafeModeException): Cannot create directory /tmp/hive/root/212090f0-e4ed-451e-a660-b5e236bb441c. Name node is in safe mode.

The reported blocks 0 needs additional 14 blocks to reach the threshold 0.9990 of total blocks 14.

The number of live datanodes 0 has reached the minimum number 0. Safe mode will be turned off automatically once the thresholds have been reached.
