Subject [jira] Commented: (SOLR-2124) SEVERE exceptions are being logged for expected PingRequestHandler SERVICE_UNAVAILABLE exceptions
Date Sun, 17 Oct 2010 20:13:22 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12921895#action_12921895
] 

Shawn Heisey commented on SOLR-2124:
------------------------------------

I spent a while trying to work out the changes required to use logOnce and have it work as
expected, got overwhelmed and lost.  Then I started with a fresh source tarball and tried
to figure out how to just get it to log an error instead of throwing an exception.  I lack
the necessary java skills to do something so basic.

> As reported by a user, if you use the PingRequestHandler, and the corrisponding helthcheck
file doesn't exist (and expected situation when a server is out of rotation) Solr is logging
a SEVERE error...
