2014-06-20 00:11:00 -0500 asked a question Sahara Configuration file

In the sahara.conf.sample the following are the first few lines

# Hostname or IP address that will be used to listen on.
# (string value)

# Port that will be used to listen on. (integer value)

What exactly is the host? Is it the machine on which sahara will be running ?

Is it possible to run sahara on one machine and all the other components like keystone, nova, glance etc etc on another machine?? Say i have a controller node which has all the components up and running and i create a VM and install only sahara on that VM. Can i do it?

Can it be integrated with ceilometer also?

How will sahara know wat vms to provision for the hadoop cluster? And will it be able to access them through ssh or any other means?

2014-06-17 02:01:05 -0500 commented question how to login in openstack dashboard using default username and Pswd

when devstack is installed it shows the usernames available and the password to login. Is it the same username and password you are using?

2014-06-16 01:57:13 -0500 asked a question Sahara with Ceph

Can sahara work with ceph? Since both ceph and sahara have the same data access model, if we implement sahara directly will it work with ceph? Or will there be some changes that have to be made?

2014-06-16 01:04:48 -0500 commented answer Sahara installation on virtual instance

Does it mean that if i install it on the controller node, it will be installed on all the virtual instances that controller node provisions or should i install it on all the virtual instance that has been created?
