Q:

MapR installation failing for single node cluster

I was referring quick installation guide for single node cluster. For this i used 20GB storage file for MaprFS but while on installation , it is giving ' Unable to find disks: /maprfs/storagefile' .
Here is my configuration file.
# Each Node section can specify nodes in the following format
# Hostname: disk1, disk2, disk3
# Specifying disks is optional. If not provided, the installer will use the values of 'disks' from the Defaults section
[Control_Nodes]
maprlocal.td.td.com: /maprfs/storagefile
#control-node2.mydomain: /dev/disk3, /dev/disk9
#control-node3.mydomain: /dev/sdb, /dev/sdc, /dev/sdd

A:

Error is resolved by adding skip-check new option after install
/opt/mapr-installer/bin/install --skip-checks new
