[jira] [Commented] (SOLR-5814) CoreContainer reports incorrect & missleading path for solrconfig.xml when there are loading problems

    [ https://issues.apache.org/jira/browse/SOLR-5814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13920139#comment-13920139 ] 

Hoss Man commented on SOLR-5814:
--------------------------------

As an example, i did this...

{noformat}
hossman@frisbee:~/lucene/4x_dev/solr/example$ echo "giberish" > solr/collection1/conf/solrconfig.xml
{noformat}

And then started solr and got this...

Note in particular the line that says: {{1570 \[coreLoadExecutor-4-thread-1\] ERROR org.apache.solr.core.CoreContainer  – Failed to load file */home/hossman/lucene/4x_dev/solr/example/solr/collection1/solrconfig.xml*}}

which is also what was front and center when i tried to load the admin UI in the browser.

If i then stop solr and naively attempt to "fix" the problem...

{noformat}
hossman@frisbee:~/lucene/4x_dev/solr/example$ mv solr/collection1/conf/solrconfig.xml solr/collection1/solrconfig.xml
{noformat}

Restarting solr gives an even less helpful variant of the same basic error (because there is no longer any useful root cause - the file really can't be found, just not in the place the main error says solr is looking) ...

>            Reporter: Hoss Man
>
> The error messages thrown by CoreContainer when there is a problem loading solrconfig.xml refer to the wrong path (leaves out "conf/").
> This is missleading users (who may not notice the root cause) into thinking they need to move their solrconfig.xml from {{collection_name/conf/solrconfig.xml}} to {{collection_name/solrconfig.xml}} at which point they still get the same error message because solr still can't find the file in the conf dir
