Question

我尝试在EC2中启动hadoop的纱线，如

$ ./start-yarn.sh

我收到以下消息

starting yarn daemons
starting resourcemanager, logging to /home/ubuntu/library/hadoop/hadoop-2.2.0/logs/yarn-ubuntu-resourcemanager-ip-x-x-x-x.out
localhost: Warning: Permanently added the ECDSA host key for IP address 'x.x.x.x' to the list of known hosts.
localhost: starting nodemanager, logging to /home/ubuntu/library/hadoop/hadoop-2.2.0/logs/yarn-ubuntu-nodemanager-ip-x-x-x-x.out

当我尝试$ jps时，我没有看到ResourceManager正在运行。当我查看yarn-ubuntu-resourcemanager-ip-x-x-x-x.out文件时，我明白了，

ulimit -a

PS：我已将ip，x.x.x.x localhost添加到/etc/hosts

中的主机列表中

我该如何调试？

Hadoop ResourceManager不以./start-yarn.sh开头
