我使用cdh(clouderadistributionhadoop)启动hdsf时,没有namenode
$ sbin/start-dfs.sh
日本:
hadoop@hekuang:~/app/hadoop-2.6.0-cdh5.7.0/sbin$ jps
10489 DataNode
10685 SecondaryNameNode
11469 Jps
名称节点日志是这样的

我尝试删除/home/hadoop/app/tmp,然后重新启动,但也没有namenode。
如果删除
<property>
<name>hadoop.tmp.dir</name>
<value>/home/hadoop/app/tmp</value>
</property>
从core site.xml,并使用默认目录,则有namenode,没有datanode

试试这个:
rm-rf/主页/hadoop/应用程序/tmp/*
hadoop namenode-格式
启动hadoop服务!!!全部启动.sh
希望这有帮助!!!干杯!!!
