Zsombor Gegesy commented on RANGER-2135:
----------------------------------------
Implementing a BaseClient subclass is not required for having a service plugin,
it's just a convention, which currently all the connector implementation
follows. If you don't need kerberos for accessing your service, then you can
safely create your own CephClient, which doesn't extends BaseClient.
Maybe moving the current login code into a 'BaseHadoopClient' child class from
BaseClient, and changing the parent class in every connector's Client class
would be a good idea. What do you think? Do you want to contribute a patch for
it?
> BaseClient forces Hadoop login

> Key: RANGER-2135
> URL: https://issues.apache.org/jira/browse/RANGER-2135
> Project: Ranger
> Issue Type: Bug
> Components: plugins
> Affects Versions: 1.0.0
> Reporter: Bolke de Bruin
> Priority: Major
>
> BaseClient does a login on instantiation that is bound to Hadoop. This
> requires service plugins to require a username/password, which is
> undocumented. It also limits the functionality to the Hadoop ecosystem.
> Suggestion:
> * Provide a default constructor
> * Make init() protected
> * Make serviceName protected
> * Make defaultConfigFile protected
> Note: I encountered this when writing a S3/Ceph plugin
