hadoop集群啟動的時候namenode顯示Connection refused
到windows下ping master 顯示傳輸中過期
ip是靜態的
ssh master 也是連接拒絕
重啟ssh服務
發現這個問題。。。

重裝ssh！！
卸載過程：
1.rpm -qa | grep ssh
ksshaskpass-0.5.3-7.el7.x86_64 openssh-clients-6.6.1p1-31.el7.x86_64 libssh2-1.4.3-10.el7_2.1.x86_64 openssh-6.6.1p1-31.el7.x86_64 openssh-server-6.6.1p1-31.el7.x86_64
2.yum -y remove +包名
安裝過程：
1.yum install -y openssh-server
由於卸載過猛，缺少安裝包，百度了好久，終於查到了
2.執行 yum install -y openssh*
3.如下圖
啟動成功后ssh master 還是沒有用，納悶。。。
測試ssh + ip 有用
問題還是出現在ip上！
我有兩個靜態ip，在 C:\Windows\System32\drivers\etc\hosts 中寫的是其中的一個，啟動時自動連接另外一個。同樣，在 /etc/hosts/ 中的ip地址也沒有改。。
