Re: [openstack-dev] [savanna] Anti-affinity
No, anti-affinity does not work that way. It allows to distribute nodes running the same process, but you can't separate nodes running different processes (i.e. master and workers).

Re: [openstack-dev] [savanna] Anti-affinity
Hi, Is it possible using anti-affinity to reserve a compute node only for master(namenode+jobtracker)?

Re: [openstack-dev] [savanna] Anti-affinity
Arindam, What exact AA configurations did you use for your cluster? Did you configure scheduler filters in Nova as it’s described here? http://docs.openstack.org/developer/savanna/userdoc/features.html#anti-affinity Also please send Savanna usage related questions to [openstack] openst...@lists.openstack.org not to openstack-dev.

Re: [openstack-dev] [savanna] Anti-affinity
Arindam, It is not achievable with the current Savanna. The anti-affinity feature allows to run one VM per compute-node only. It can not evenly distribute VMs in case the number of compute nodes is lower than the desired size of Hadoop cluster. Dmitry 2013/12/5 Arindam Choudhury > HI, > > I have 11 compute nodes.
