Setting up high-availabilty plugin

[Cobin Bluth]

Hi Gerrit Team,

I'm struggling to set up gerrit high-availabilty with the plugin, and I'm hoping someone can help.

My project is migrating a singleton Gerrit instance version 3.11.3 to a dual instance with high-availabilty. I'm using global-refdb.jar marked stable-3.11/lastSuccessfulBuild from gerrit-ci Jenkins, and putting it in the /lib dir, I'm also grabbing high-availabilty.jar stable-3.11/lastSuccessfulBuild from the same place and putting it in the /plugins dir, and I'm giving it a very basic config; main.sharedDirectory = $sharedDir ; peerInfo.strategy = "static" ; ref-database.enabled = "true" ; peerInfo.static.url = $peer2 .

The error I'm facing is that the logs show WARN : Cannot load plugin high-availabilty : Unable to create injector : [Guice/MissingConstructor]: No injectable constructor for type SharedRefDbConfiguration class does not have @Inject annotated constructor or a no-arg constructor

I'm wondering if the plugins/modules are not the right version for Gerrit, should I be trying to use Gerrit version 3.11.4 or 3.11.5?

Any pointers or ideas?

Thanks,

-Cobin

I'd try the latest 3.11.5 release, if that fails with the same error try your own build of the stable-3.11 branch.

 

Thanks,

Can you share the full stack trace and the full configuration?
Have you checked if your configuration looks like the sample one at [1]?

HTH

Actually, I think im missing a refdb configuration, as seen here near the bottom: https://gerrit.googlesource.com/plugins/high-availability/+/HEAD/src/main/resources/Documentation/about.md

I will setup zookeeper to see if that's what it wants.
