Hi,

Is it possible using anti-affinity to reserve a compute node only for master(namenode+jobtracker)?

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.

HI,

I have 11 compute nodes. I want to create a hadoop cluster with 1 master(namenode+jobtracker) with 20 worker (datanode+tasktracker).

How to configure the Anti-affinty so I can run the master in one host, while others will be hosting two worker?


I tried some configuration, but I can not achieve it.

Regards,
Arindam
