Hi, I tried to run hadoop in standalone mode according to hadoop online document. But, I get error message as below. I run command "./bin/hadoop jar hadoop-examples-1.1.1.jar pi 10 100".
*13/01/18 01:07:05 INFO ipc.Client: Retrying connect to server: localhost/ 127.0.0.1:8020. Already tried 9 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS) java.lang.RuntimeException: java.net.ConnectException: Call to localhost/ 127.0.0.1:8020 failed on connection exception: java.net.ConnectException: Connection refused * I disabled ipV6, firewall on my linux machine. But, i still get this error message. localhost is bound with 127.0.01 . core-site.xml and mapreduce-site.xml are empty as they are not modified. Anybody can give me a hint if I need to do some specific configuration to run hadoop in standalone mode? thanks and regards, Yiyu
