[jira] Commented: (SOLR-1981) solr.xml should fail to load if multiple cores with the same name

["Hoss Man (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-1981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12884837#action_12884837 ] 

Hoss Man commented on SOLR-1981:
--------------------------------

Note: what i'm propossing here actually breaks back-compat in a way that i think is good.

at the moment, if you declare multiple cores with the exact same name, solr will initialize the first, then initialize the second, which will shutdown the first -- in effect, silently ignoring the first declaration.

I'm proposing a hard failure during solr.xml config parsing, before any SolrCores are ever initialized.
