[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-614) FileNotFoundException during slave synchronization with source

[Hardy Ferentschik (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38939#action_38939 ] 

Hardy Ferentschik commented on HSEARCH-614:
-------------------------------------------

Since I haven't seen this mentioned - the problem only occurs on {{start()}}. If this situation occurs after the directory is started the error is logged and the slave index directory does not get switched - skipping one synchronization. On {{start()}} the assumption is that the slave has to be able to successfully get an initial copy of the index. Depending on when master and slave are getting started this could even happen with "reasonable" refresh properties.
One solution would be to add some retry operation for {{start()}}. is it worth it? Maybe it is better to fail early. In a proper application setup you would (hopefully) have some sort of monitoring/startup harness around your apps.

> The current file synchronization mechanism in the FSSlaveDirectoryProvider has the potential to throw a FileNotFoundException if the source file it's copying is deleted before the copy operation completes.
