Error when adding MongoDB as source

1

Hi,

I am trying to add MongoDB as a new source.
My config is:

  • Dremio: 1.2.1-201710030121530889-8e49316
  • MongoDB: v3.6.0-rc1 - localhost/27017 - no authent

I get the following error in the UI: Failure while attempting to register source: Failure setting up new storage plugin configuration for config com.dremio.plugins.mongo.MongoStoragePluginConfig@6a7270ce

In server.log, there is an exception and the last lines are:

Unfortunately has an issue with parsing Mongo version with “-rc” (non-numeric another words). I don’t see any workaround without code change. I will file a JIRA to fix it. Not sure if you could downgrade/upgrade Mongo to have just numeric version meanwhile

Hi Bruno!

Hopefully 3.6 ships soon. :slight_smile:

I have downgraded Mongo to 3.4 and it works. I will retry with 3.6 in a few days :slight_smile:
Thanks !
