HI , I am trying to step up a hadoop cluster on 3GB machine and using hadoop 0.18.3 and have followed procedure given in apache hadoop site for hadoop cluster. In conf/slaves I have added two datanode i.e including the namenode vitrual machine and other machine virtual machine (datanode) ..... and have set up passwordless ssh between both virtual machines ..... But now problem is when I run command :
bin/hadoop start-all.sh It start only one datanode on the same namenode vitrual machine but it doesn't start the datanode on other machine..... in logs/hadoop-datanode.log i get message INFO org.apache.hadoop.ipc.Client: Retrying connect to server: hadoop1/192.168.1.28:9000. Already tried 1 time(s). 2009-05-09 18:35:14,266 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: hadoop1/192.168.1.28:9000. Already tried 2 time(s). 2009-05-09 18:35:14,266 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: hadoop1/192.168.1.28:9000. Already tried 3 time(s). . . . . . . . . . . . . I have tried formatting and start the cluster again .....but still I get the same error. So can any one help in solving this problem. :) Thanks Regards Ashish Pareek
