Environment
LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch: graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: RedHatEnterpriseServer
Description: Red Hat Enterprise Linux Server release 6.4 (Santiago)
Release: 6.4
Codename: Santiago
SSH Configuration
Install root, it is SSH keyless
Disk Configuration
On each node (the real environment needs raw disks, but there are no such diskw now):
mkdir /opt/mapr-disks
dd if=/dev/zero of=/opt/mapr-disks/loop0 bs=1G count=8
/sbin/losetup -f
/sbin/losetup /dev/loop0 /opt/mapr-disks/loop0
echo /dev/loop0 > /tmp/disks.txt
or using the file directly:
mkdir /opt/mapr-disks
dd if=/dev/zero of=/opt/mapr-disks/loop0 bs=1G count=8
echo /opt/mapr-disks/loop0 > /tmp/disks.txt
Ensure no NFS server running no output for
"rpcinfo -p | grep nfs"
Download Configuration
create /etc/yum.repos.d/maprtech.repo on each node
[maprtech]
name=MapR Technologies
baseurl=http://package.mapr.com/releases/v3.0.2/redhat/
enabled=1
gpgcheck=0
protect=1
[maprecosystem]

Install the packages
Install management node:
yum install mapr-cldb mapr-fileserver mapr-jobtracker mapr-nfs mapr-tasktracker mapr-webserver mapr-zookeeper
Install compute node run:
yum install mapr-fileserver mapr-tasktracker mapr-zookeeper
Note: Add /etc/yum.conf with proxy=http://IP:port if necessary.
Mount disk to MapR-FS
/opt/mapr/server/configure.sh -C <ManageNodeIP> -Z <ManageNodeIP>,<ComputeNodeIP> -u root
/opt/mapr/server/disksetup -F /tmp/disks.txt
Start Zookeeper:
