Re: Ansible module for Ambari

[Jabir Ahmed <ja...@gmail.com>]

From my experience over using puppet , ambari and ansible for managing
hadoop, its better to stop using ambari and just write your own ansible
scripts to deploy the cluster & configs.

It would surely give you more control over the deployment also it would
give you a deeper understanding of how an incremental update happens
internally.

Thanks
