我正在尝试启动namenode,但它一直显示:无法启动namenode.java.net.BindException:地址已在使用中;

netstat -a | grep 9000

回报

tcp 0 0 :9000 *: LISTEN
tcp6 0 0 [::]:9000 [::]:* LISTEN

这是正常的还是我需要杀死其中一个进程？

名称节点在安装后启动并运行,并在运行WordCount作业后突然停止工作.我已经尝试重新启动VM并多次格式化namenode,但这没有帮助.

hdfs-site.xml如下:

dfs.replication 1 dfs.namenode.name.dir file:/// usr/local/hdfs/namenode dfs.datanode.data.dir file:/// usr/local/hdfs/datanode

namenode日志如下:
