actually i tried to add new node to cluster i fooled this steps
step 1: Log into the node that you will add to the cluster, as the user root.
step 2: On the new node, add the user and group mapr. Remember, you must use the same UID and
GID that is used on the cluster nodes. Set the mapr password to match its password on the
other nodes in the cluster.
step 3: rsync -avr /etc/yum.repos.d/mapr* <new node IP>:/etc/yum.repos.d
step 4: rpm --import http://package.mapr.com/releases/pub/maprgpg.key
step 5: yum install -y mapr-webserver mapr-fileserver mapr-nodemanager
step 6: From the new node, run configure.sh:
# /opt/mapr/server/configure.sh –C <cldb list> -Z <zk list> \
-N <cluster name> -M7
here in new node server directory is not found..
