I am getting below message when I start the Hive. I just installed CDH 5.4.
from cloudera manager:
Canary test failed to create file in directory /tmp/.cloudera_health_monitoring_canary_files.
Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.SafeModeException): Cannot create directory /tmp/hive/hdfs/5502ca90-629f-4c7e-afd5-dada9535d15c. Name node is in safe mode.
The reported blocks 404 needs additional 504 blocks to reach the threshold 0.9990 of total blocks 908.
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.
How do I fix it?
