In hadoop 2.6 the namenode must be on , but hadoop 1.1.2 the namenode is down is ok.

below is the configuration.

<property>
        <name>fs.default.name</name>
        <value>ceph://ceph0:6789/</value>
   </property>

 in hadoop2.6 the raise exceptions like this:

15/07/28 11:26:55 INFO mapreduce.Cluster: Failed to use org.apache.hadoop.mapred.YarnClientProtocolProvider due to error: Error in instantiating YarnClient
java.io.IOException: Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses.

How can i use it in hadoop2.6?
