Hi, I have a general question. All of our metadata (CM, Hive MS, Oozie, Navigator, etc) is stored in a local MySQL instance on the Cloudera Manager host (see list of DB's below). If this host were to fail, or the MySQL service were to become unavailable for a period of time, would all of the core cluster services (excluding CM services) continue to function? I am unclear if we need to look at implementing a MySQL cluster to maintain cluster uptime. Thank you!
Edit: I should add that we are currently replicating MySQL to a slave.
Thank you @EricL . Makes sense. We currently have MySQL set up in a master/slave config. But it looks like even with that... if the Master is offline, you have to manually edit the CM config to point to the slave. There is no where in CM (that I see) to add a slave/secondary MySQL hostname.
So I assume that is why you reference setting up MySQL in a "cluster" configuration and not just master/slave replication - correct? Thank you.
