Subject: Issue: Namenode is in safe mode


I have created a hadoop cluster with two nodes (A and B). 'A' act both as namenode and datanode,
and 'B' act as datanode only. With this setup, I could store, read files. Now, I added one
more datanode 'C' and relieved 'A' from datanode duty. This means, 'A' act only as namenode,
and both B and C act as datanodes. Now, I tried to create a directory, it says

' org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot create directory Name node
is in safe mode'

Can someone tell me why the namenode now is in safe mode?

With thanks and regards
