[jira] Created: (SOLR-1206) Default ping is not useful

Default ping is not useful
--------------------------

                 Key: SOLR-1206
                 URL: https://issues.apache.org/jira/browse/SOLR-1206
             Project: Solr
          Issue Type: Improvement
          Components: search
    Affects Versions: 1.3
         Environment: Debian linux / jetty
            Reporter: Brian Whitman
            Priority: Minor


We recently had a solr server go down as the underlying disk (where the data was) stopped responding. The server was still running and the admin GUI worked, as did the ping query. But any actual query (like select?q=*:*) would hang indefinitely.

I know that you can modify the ping query to be more robust, but I would like to suggest that the default shipping ping tries to access data, as I imagine that's what your average user is testing when they "ping solr"

[jira] Commented: (SOLR-1206) Default ping is not useful

Posted by "Hoss Man (JIRA)" <ji...@apache.org>.
    [ https://issues.apache.org/jira/browse/SOLR-1206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12722798#action_12722798 ] 

Hoss Man commented on SOLR-1206:
--------------------------------

I'm not sure how a different "default" (note: it's not really a default, it's an example ... there is no default) query would have helped in the situation described ... q=solrpingquery requires executing a search against the index just like any other query string.

If you were seeing ping succeed, but q=*:* was failing then my guess would be that the ping query was being served from the cache.
