Hadoop Datanode启动，但不启动namenode
经过一番努力，我终于在伪分布式节点中使用了hadoop，一个Hadoop Datanode启动，但不启动namenode,hadoop,hdfs,Hadoop,Hdfs,经过一番努力，我终于在伪分布式节点中使用了hadoop，一个namenode和一个jobtracker工作正常（在http://localhost:50070和http://localhost:50030） 昨天我尝试用以下命令重新启动我的namenode，datanode，等等： $hadoop namenode -format $start-all.sh 而jps为我提供了以下输出： 17148 DataNode 17295 SecondaryNameNode 17419 JobTrack
namenodejobtrackerhttp://localhost:50070http://localhost:50030namenodedatanode$hadoop namenode -format
