Newbie With Linux Clustering, Need Help!!
Hi All,
I am new user here and a new one to try clustering with Ubuntu nodes, and need help. If I should be in another place please mention.
I have a two nodes with Ubuntu 14.04 installed on them. I need to make a cluster consisting of these two nodes with purpose of experimentation with cloud and HPC technologies.
My question is , is there something basic I should be doing without getting into big names like Hadoop, Openstack , Mesos etc, which I assume should be discussed after a simple cluster is setup?
Can someone point me or mention a way to setup a simple test cluster of the two nodes , which run ubuntu 14.04, and then mention what to install to keep track of resources and running HPC applications on the cluster.
Many thanks and sorry if this is naiive. I intend not to remain so anymore
Appreciate any help.

cmhaltcl
cmhaltcl(1m) cmhaltcl(1m) NAME
cmhaltcl - halt a high availability cluster SYNOPSIS
cmhaltcl [-f] [-v] DESCRIPTION
cmhaltcl causes all nodes in a configured cluster to stop their cluster daemons, optionally halting all packages or applications in the process. To stop a cluster, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configuration file. See access policy in cmquerycl(1). This command will halt all the daemons on all currently running systems. If the user only wants to shutdown a subset of daemons, the cmhaltnode command should be used instead. Options cmhaltcl supports the following options: -f Force the cluster to shutdown even if packages or group members are currently running. This will cause the packages and group members to be halted. If a package halt fails, the cluster halt will also fail. -v Verbose output will be displayed. RETURN VALUE
cmhaltcl returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
Halt the cluster daemons: cmhaltcl AUTHOR
