Mark Miller commented on SOLR-4725:
-----------------------------------
I think dataDir should continue to be supported. There is not much reason to
rip it.
name should be removed.
> Should we stop supporting "name" and "dataDir" in the autodiscover mode?

> Key: SOLR-4725
> URL: https://issues.apache.org/jira/browse/SOLR-4725
> Project: Solr
> Issue Type: New Feature
> Affects Versions: 4.3, 5.0
> Reporter: Erick Erickson
> Assignee: Erick Erickson
> Priority: Blocker
>
> Making this a blocker so we resolve it. Should be quick to code if we have
> consensus, maybe nothing at all to do here.
> I'm not too happy with the fact that the new core discovery process has two
> real gotcha's. The individual core.properties file can define 'name' and
> 'dataDir'. It seems too easy to either use the same name for two different
> cores or use the same dataDir, just copy the core.properties file around and
> fail to edit one them. In large installations this could be a bear to track
> down.
> Straw-man proposal is the we remove support for them both in discovery mode.
> The name defaults to the directory in which core.properties is found and the
> data dir is immediately below there.
> Currently, there are checks to fail to load either core if either 'name' or
> 'dataDir' is defined in more than one core. I think the error reporting is
> weak, you probably have to look in the log file and there should be a way to
> get this in the admin UI at least.
> Maybe the right thing to do is just leave it as-is and emphasize that
> specifying the dataDir and name is expert level and you have to get it right,
> but I wanted to get wider exposure to the problem before we push 4.3 out.
