Subject [jira] [Commented] (WHIRR-378) Auth fail when creating a cluster from an EC2 instance
Date Fri, 23 Sep 2011 02:17:26 GMT

    [ https://issues.apache.org/jira/browse/WHIRR-378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13113110#comment-13113110

Adrian Cole commented on WHIRR-378:

I just ran this on 0.7.0, and received a different error ( a transient one related to ec2
ssh keys [1], which ended up having us create a 4th node ).

However, things operated did come up without the ssh error you mentioned.  How are your ssh
keys setup? Do you have a ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub file in correct form? Are you
destroying your cluster through whirr or elsewhere?

I'll also try with 0.6.0 now
