Using the MapR Subnet and MapR External Advanced Options
Using the Installer advanced options available under Node Configuration, you can restrict the cluster to a subset of network interface cards (NICs) or specify public IP addresses that can be used with the cluster nodes.
Using these options in the Installer has the same effect as manually inserting the
MAPR_SUBNETS and MAPR_EXTERNAL environment variables into the env_override.sh
file on all
nodes.
- MapR Subnet
- Allows you to set a subnet mask to restrict cluster services to certain interfaces. The
values specified in this field are used to populate the MAPR_SUBNETS environment
variable.Specify one or more comma-separated subnet masks. For example:
10.10.15.0/24,10.10.16.0/24
The information on this page is specific to the web-based Installer. To configure the MAPR_SUBNETS environment variable for a manual installation, see Designating NICs for HPE Ezmeral Data Fabric.
- MapR External
- Allows you to specify external IP addresses for the CLDB, file system, and MAST Gateway nodes. Do NOT use DNS names. Specify a comma-separated list of tuples of host names and external IP addresses. For example:
node1:1.1.1.1,node2:1.1.1.2,node3:1.1.1.3
The specified node names need to match the host name you specified for the host earlier in Node Configuration. The information on this page is specific to the web-based Installer.
