我正在尝试在伪分布式环境下在ubuntu上安装hadoop。 start-dfs.sh （给我一个错误）

Starting namenodes on [10.1.37.12]

10.1.37.00: ssh: connect to host 10.1.37.12 port 22: Connection timed out

localhost: starting datanode, logging to /usr/local/hadoop/logs/hadoop-superuser-datanode-superuser-Satellite-E45W-C.out

Starting secondary namenodes [0.0.0.0]

0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop/logs/hadoop-superuser-secondarynamenode-superuser-Satellite-E45W-C.out

我已将端口22添加到防火墙
jps输出：
2562数据节点
3846日元
2743次要名称节点
有人能帮我明白吗，这里怎么了？
