Subject [jira] Commented: (SOLR-1730) Solr fails to start if QueryElevationComponent config is missing
Date Wed, 30 Jun 2010 22:20:50 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12884078#action_12884078
] 

Grant Ingersoll commented on SOLR-1730:
---------------------------------------

I don't understand why it needs to even do this, what benefit is there to the QEC if it doesn't
have an elevation file?  Seems like it should just disable itself or throw an exception and
fail.

> This does not work though, as asking for the newest searcher causes a request to be submitted
to Solr before its ready to handle it:

> {code}
> The SearchHandler has not yet been core informed (as the QueryElevationComponent causes
this as its getting core informed right before the SearchHandler) and so its components arraylist
is still null.
