Looking at to code, it pulls from a backup and restores the state. It manages the cluster slave and master states via zookeeper. When the master fails a slave is promoted.
So, in order to run this you need zookeeper, hdfs, and mesos. Its a great solution, but not for everyone.
- jpgvm 11y agoTo be fair, if you have Mesos it's highly likely you already have HDFS, ZK is a dependency of Mesos. Though it's not strictly necessary to run HDFS a lot of Mesos native applications and frameworks already expect it. The thing is you can often run HDFS on your Mesos slaves so it ends up stacking up quite nicely, atleast in small deployments.
- merb 11y agoHow is HDFS quite nicely in small environments? I mean a minimal HA deployment of HDFS contains at least 5 nodes. 2x Namenode, 3x Data Nodes. Sorry but for "starting out small" this is definitely too much.
- jpgvm 11y agoI don't see how Mesos is going to be useful to you with less than 5 servers.
