[jira] [Commented] (SOLR-4890) Can't find (or read) directory to
add to classloader: /non/existent/dir/yields/warning (resolved as:
/non/existent/dir/yields/warning).
[ https://issues.apache.org/jira/browse/SOLR-4890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13672818#comment-13672818 ]
Shawn Heisey commented on SOLR-4890:
------------------------------------
Previous Solr versions would silently ignore lib directories that didn't exist, and the ignored entry at the time had an expletive in it. With the newest version, it issues a warning. The line is purposely not commented, and the reason is encoded right in it's name - it doesn't exist, which gives you a warning. The log entry is at the WARN level, it's not an error.
It could be argued that this should not be uncommented in the config, but it is not an error and doesn't prevent startup, it's there to illustrate what happens with a non-fatal misconfiguration.

> I just did a fresh install of Solr 4.3.0 twice. Both times, the default build yielded this in Logging:
> Can't find (or read) directory to add to classloader: /non/existent/dir/yields/warning (resolved as: /non/existent/dir/yields/warning).
> This appears to come from line 87 in solrconfig.xml for collection1, which I think is supposed to be commented out. Or maybe it has some other purpose. Either way, the comments in that file, at least regarding this line, are totally unhelpful.
