我安装了hadoop单节点，现在我用 start-dfs.sh 命令。
但是jobotracker和tasktracker并没有出现在 jps 命令，所以他们似乎没有开始。
你明白为什么吗？我正在安装2.6.2版。。。
执行命令后 start-dfs.sh ，将显示：
[hadoopadmin@hadoop ~]$ start-dfs.sh

不再有jobtracker和tasktracker了。我们有nodemanager和resourcemanager。在这里您只是启动了dfs服务而不是启动了yarn服务，来启动yarn服务运行
start-yarn.sh只有Yarn相关的服务才会启动。如果要启动所有服务，请运行
start-all.sh（不太好的做法）
