发现是 5576 这个NodeManager 的端口被占用了。通过如下另种方式可以查询到process并kill:

方法一 : # lsof -i :5576 可以查看到占用端口5576的程序PID , kill -9 PID 处理，再启动就不会报错了。

方法一：如果NodeManager异常关闭导致未释放 ps -ef | grep NodeManager 。

备注：

netstat -anp       显示系统端口使用情况
lsof -i   :端口        显示占用该端口的进程情况

startNodeManager端口被占用：java.net.BindException: Address already in use
