Hi,
Newbie alert.
I am trying to launch a 5 node cluster with Whirr. I get the following
message during a launch:
Unexpected error while starting 4 nodes, minimum 4 nodes for
[hadoop-datanode, hadoop-tasktracker] of cluster HCluster1
*java.util.concurrent.ExecutionException:
java.lang.IllegalArgumentException: no private key configured for:
[region=us-east-1, name=jclouds#HCluster1#us-east-1#26]; please use
options.overrideLoginCredentialWith(rsa_private_text)*

While the cluster eventually does startup I am unable to do a hadoop fs
-ls. Before I debug that further wondering if the error message above is
harmless or maybe the root cause of my some of my issues.
My hadoop.properties: (I did create the two env variables and also did the
rsa key gen)
whirr.cluster-name=HCluster
whirr.instance-templates=1 hadoop-jobtracker+hadoop-namenode,4
hadoop-datanode+hadoop-tasktracker
whirr.provider=aws-ec2
whirr.identity=${env:AWS_ACCESS_KEY_ID}
whirr.credential=${env:AWS_SECRET_ACCESS_KEY}
whirr.private-key-file=${sys:user.home}/.ssh/id_rsa
whirr.public-key-file=${sys:user.home}/.ssh/id_rsa.pub
whirr.cluster-user=huser
Any help is appreciated.
Thx,
LR
