>    Affects Versions: 2.0.0
>            Reporter: Jonathan Hurley

>            Priority: Critical

> The following are properties that are exposed via {{ambari.properties}} and which have
hard coded defaults in the Java code but appear no where in {{ambari.properties}} in a default
installation:
> {noformat}
> server.jdbc.connection-pool=c3p0
> server.jdbc.connection-pool.acquisition-size=5
> server.jdbc.connection-pool.max-age=0
> server.jdbc.connection-pool.max-idle-time=14400
> server.jdbc.connection-pool.max-idle-time-excess=0
> server.jdbc.connection-pool.idle-test-interval=7200
> {noformat}
> We should write these properties into {{ambari.properties}} at install-time when configuring
the database. MySQL will get c3p0 by default while other database providers will get "internal"
(JPA) as their pooling mechanism.
