報錯了：ssh: connect to host localhost port 22: Connection refused
在執行start-all.sh時報如下的錯誤：
root@ubuntu:/home/sd1700092/skyone/hadoop-1.2.1/bin# start-all.sh
Warning: $HADOOP_HOME is deprecated.

有人遇到過么？

我也遇到了和樓上相同的問題，少了兩個進程
同時，運行 hadoop fs -ls /的時候顯示以下錯誤
ls: Call to ubuntu/127.0.1.1:9000 failed on connection exception: java.net.ConnectException: Connection refused
不知道應該怎樣更改配置文件，求解
（我的localhost的名字是ubuntu）

配了好久解決了上個問題，現在每步操作都做好了，但看JPS只有這幾個東西。。
root@ubuntu:/home/sd1700092/skyone/hadoop-1.2.1/bin# jps
6501 SecondaryNameNode
6906 Jps
6312 DataNode
6785 TaskTracker
請問另外幾個去哪里了？該怎么設置才能也出來，謝謝

我去安裝sudo apt-get install openssh-server時接著報錯，
Reading package lists... Done
Building dependency tree ? ? ??

我已經獲取根用戶了，為什么還是Connection refused
