Hi,

&nb= sp;

I have created a hadoop clu= ster with two nodes (A and B). ‘A’ act both as namenode and dat= anode, and ‘B’ act as datanode only. With this setup, I could s= tore, read files. Now, I added one more datanode ‘C’ and reliev= ed ‘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 d= irectory, it says

 =

‘ org.apache.hadoop.hdfs.serv= er.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

Balachandar
