Following the instructions for cluster installations (here I used only 1 machine not the VM version) at
this is what happened:

1) I have created the "/opt/install-mapr" directory with the file "mycluster.roles" inside it containing:

" mapr-nfs,mapr-fileserver,mapr-metrics,mapr-tasktracker,mapr-jobtracker,mapr-cldb,mapr-zookeeper, mapr-webserver /dev/sdb,/dev/sdb1,/dev/sdc"

I'm suspicious the above has an error.

2) Then I ran the command$  ./maprinstall -R mycluster.roles -F -u root

And got the following request to enter CLDB and zookeeper machines as follows:

Logging to /opt/mapr/logs/maprinstall.log, /opt/mapr/logs/maprinstall.log.summary
Logging to /opt/mapr/logs/maprinstall.log, /opt/mapr/logs/maprinstall.log.summary

   Could not find MapR packages in the repository. Configure the repository correctly and retry.

     Install failed on the following nodes:

I checked the errors in "/opt/mapr/logs/" but there are lots of lines to look at.

Where do you think my mistake is?
