运行:
./bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-*.jar grep input output 'dfs[a-z.]+'
出现:
java.net.ConnectException: Call From yongbin-Lenovo/127.0.1.1 to localhost:9000 failed on connection exception: java.net.ConnectException: 拒绝连接;
请问各路大牛这个可能是什么原因?就是按照http://www.powerxing.com/install-hadoop/步骤来的,之前好好的现在不行了
