I have successfully installed MapR Cluster. However, in the MCS I could able to see only one node instead of 3. I searched all the local directories and observed that in the node which is up, audit, logs, metrics folders were there but in the other folders named by other node names, these folders are not there.
[root@maprnode1 maprnode1]# pwd
[root@maprnode1 maprnode1]# ls
audit logs metrics
