[jira] [Commented] (SOLR-12386) Test fails for "Can't find
resource" for files in the _default configset
[ https://issues.apache.org/jira/browse/SOLR-12386?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17100807#comment-17100807 ]
David Smiley commented on SOLR-12386:
-------------------------------------
For the case of an incomplete configSet (i.e. one that didn't exist and is in the process of coming into existence), I think the solution is somewhat simple: SOLR-14446 (Use Zk.multi when uploading configSets) in combination with a retry mechanism on creation of ZkSolrResourceLoader that ensures the ZK based configSet dir exists. That retry mechanism would probably do a Zk.sync() in-between. Not sure if that retry strategy should go in SOLR-14446 or be another issue.
A separate issue(s) is more comprehensively thinking about how to deal with _modifications_ to a configSet – e.g. for schema mutations, or otherwise. That would probably involve a Zk.sync as well but with as yet unspecified means to ensure we don't call it too often.

> Some tests, especially ConcurrentCreateRoutedAliasTest, have failed sporadically failed with the message "Can't find resource" pertaining to a file that is in the default ConfigSet yet mysteriously can't be found. This happens when a collection is being created that ultimately fails for this reason.
