Hi, You can run Oozie without an HA database. A non-HA MySQL, Oracle, or Postgres database will work just fine, other than if the database goes down, your Oozie becomes unavailable (i.e. the database is a single point of failure).
The reason you can't use Derby for Oozie HA is because it doesn't support multiple concurrent connections. In Oozie HA, each Oozie server connects to the database, so there are multiple connections; Derby doesn't allow that so only one of the Oozie servers would be able to connect. - Robert On Tue, Feb 18, 2014 at 1:16 AM, Anand Vidwansa <[email protected]> wrote: > Hi, > > I wanted to know if there is a way to configure oozie HA support with derby > as database. > I understand oozie HA support expects an HA database. > But, is there a way to use native replication in derby to replicate data > between > two hosts and switch to secondary store in case oozie fails over? > > Any help is appreciated! > > Thanks, > Anand >
