Re: Read namenode data from primary memory
Hi Aditya:
   This command line may help you:

     hadoop dfsadmin --saveNamespace

     you should firstly perform it in safe mode.

    The corresponding design and implementation is described here:
https://issues.apache.org/jira/browse/HADOOP-4826
yours,
Ling Kun
