环境:ubuntu 14.04,hadoop 2.6

当我键入start-all.sh和jps,DataNode不会列出终端上

>jps
9529 ResourceManager
9652 NodeManager
9060 NameNode
10108 Jps
9384 SecondaryNameNode

根据这个答案:Datanode进程没有在Hadoop中运行

我尝试了最好的解决方案

• bin/stop-all.sh (or stop-dfs.sh and stop-yarn.sh in the 2.x serie)
• rm -Rf /app/tmp/hadoop-your-username/*
• bin/hadoop namenode -format (or hdfs in the 2.x series)

但是,现在我明白了:

>jps
20369 ResourceManager
26032 Jps
20204 SecondaryNameNode
20710 NodeManager

如你所见,即使NameNode是失踪,请帮助我.
