Now that most of the new nodes have been added to the cluster (we are only waiting on 2 more), we have some room to repurpose a few of the older nodes. First up, I'd like to repurpose one of these as the Hive / Oozie server.
- Decommission an old Hadoop node
- Reinstall node.
- Stop Oozie, Hive, MySQL move to newly installed node, and puppetize.
- Make sure MySQL DB is properly backed up.
- Adjust Hive heapsizes in role::analytics::hive::server
