    My environment is hadoop 0.23.5 cluster( three nodes: two for namenode, one for nodemangement & resourcemangement and both three nodes are datanode)

    I google all the answers about how to leave namenode safemode and got the same answer :

    hadoop dfsadmin -safemode leave
    

    because I run hadoop 0.23.5 on ubuntu 12.10 and it seems that need to be changed to :

    hdfs dfsadmin -safemode leave
    

    but I still got the error below...

    safemode: FileSystem file:/// is not an HDFS file system
