dobesv commented on issue #2001: DRILL-7547: Support credentials store for mongo connections URL: https://github.com/apache/drill/pull/2001#issuecomment-592610782 > 1. What happens if the user has multiple mongo storage plugins? Are the creds carried over to all of them? If a user specifies creds in the storage plugin config does it overwrite the config file? The configuration key is based on the plugin name, actually. `mongo` is the default name for the storage plugin, but if you had another one named `mongo-prod` you would set `drill.exec.store.mongo-prod.username`. If the connection string already has credentials, this will not replace them. > 2. This isn't for this PR, but would it make sense for us to do this for other storage plugins that are not likely to have multiple instances? Kudu, HBase or Hive for instance? I think it is an OK approach for any plugin that has credentials currently stored in ZooKeeper. Note that the key I use is based on the plugin's name so you can setup multiple.
