> Using MySQL too is an external dependency, just like Zookeeper. I wonder if we should make StateStoreDrive IA.Public for others to extend it. Similar to MySQL, one should be able to use postgres and other databases too, but each impl might bring too much of external dependencies in hadoop, making the dependency management difficult over a period of time (more transitive CVE exposures?). WDYT? For this one though, it's still manageable as mysql dependencies are already added (for token store impl). > > cc @goiri @slfan1989 Yes, I agree it an external dependency. The desire it to depend on just one system MySQL for both the StateStore and DelegationTokens(HADOOP-18535). So StateStoreDriver is already public and can be configured with `dfs.federation.router.store.driver.class` . I just tested moving my new class to a separate package and all the utilities I accessed are still reachable. -- This is an automated message from the Apache Git Service.
