Failed to start Name Server for HDFS. with the following error "java.io.IOException: NameNode is not formatted."

Try to follow "http://www.cloudera.com/documentation/manager/5-0-x/Cloudera-Manager-Managing-Clusters/cm5mc_nn.html" to format the name node directory. but there is no such action in the action menu for the selected Name node instance.
