-------------------------------

             Summary: Replace c3p0 connection pool with HikariCP, upgrading MySQL connector
and Eclipselink
                 Key: RANGER-2895
                 URL: https://issues.apache.org/jira/browse/RANGER-2895
             Project: Ranger
          Issue Type: Improvement
          Components: admin, Ranger
            Reporter: RickyMa


We should replace c3p0 with [HikariCP|[https://github.com/brettwooldridge/HikariCP]]. HikariCP
is much faster and less error prone. HikariCP is more popular with 13.2k+ stars on its github.
There were no more new commits since Nov 18, 2019 in [c3p0|[https://github.com/swaldman/c3p0/commits/master]].

[MySQL connector|[https://github.com/mysql/mysql-connector-j]] and [Eclipselink|[https://github.com/eclipse-ee4j/eclipselink]]
should be upgraded to the latest stable versions as well to include many essential bugfixes.
