Hadoop cluster 재시작

이런 에러가 발생해서

$> hadoop dfsadmin -report
13/04/04 20:34:54 INFO ipc.Client: Retrying connect to server: localhost/127.0.0.1:9000. Already tried 0 time(s).
13/04/04 20:34:55 INFO ipc.Client: Retrying connect to server: localhost/127.0.0.1:9000. Already tried 1 time(s).

재시작을 찾다가..보니 잘 뜨는 군요.

#start cluster
$> hadoop/bin/start-all.sh
