Hi, When NN is in safe mode, you get a read-only view of the hadoop file system. ( since NN is reconstructing its image of FS ) Use "hadoop dfsadmin -safemode get" to check if in safe mode. "hadoop dfsadmin -safemode leave" to leave safe mode forcefully. Or use "hadoop dfsadmin -safemode wait" to block till NN leaves by itself.
