Error while starting Hive

rio — Fri, 16 Sep 2022 09:41:43 GMT

Hi,

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.

from server:

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?

Thanks!

"Name node is in safe mode" means not enough datanodes have reported in
with the block reports. Visit the Namenode UI to find out which datanodes
have not reported in yet.

Alternatively one or more datanodes have lost blocks from their local
filesystem. You can run the "sudo -u hdfs hdfs fsck / -listcourrptblocks"
command to see which files are corrupt

when I run:

sudo -u hdfs hdfs fsck / -listcourrptblocks

i get:

fsck: Illegal option '-listcourrptblocks'

probably a typo. "courrpt" should be "corrupt"
