How to exit NameNode safe mode?

0 votes

I am trying to make a directory in HDFS but getting an error saying NameNode is in safe mode

hdfs# bin/hadoop fs -mkdir test

mkdir: org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot create directory /user/root/test. Name node is in safe mode.

After some browsing I found this command to leave safe mode, but still I am getting the error.

hdfs# bin/hadoop fs -safemode leave
safemode: Unknown command

Can someone me help me out?

The error you are getting is because -safemode is not an argument of hadoop fs, but is the argument of dfsadmin

You need to use the following command to leave the safemode forcefully:

hdfs dfsadmin -safemode leave

You can also use hadoop dfsadmin, but it has been deprecated
