[jira] [Commented] (SOLR-11616) Backup failing on a constantly
changing index with NoSuchFileException
[ https://issues.apache.org/jira/browse/SOLR-11616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16901938#comment-16901938 ]
Andrian Jardan commented on SOLR-11616:
---------------------------------------
It seems like this issue is back in 7.7.2. We are using the official 7.7.2 container, and we see this during backups sometimes:
Is it a regression, or there's something new ?

> Key: SOLR-11616
> URL: https://issues.apache.org/jira/browse/SOLR-11616
> Project: Solr
> Issue Type: Bug
> Reporter: Varun Thacker
> Assignee: Varun Thacker
> Priority: Major
> Fix For: 7.2, 8.0
>
> Attachments: SOLR-11616.patch, SOLR-11616.patch, solr-6.3.log, solr-7.1.log
>
>
> As reported by several users on SOLR-9120 , Solr backups fail with NoSuchFileException on a constantly changing index.
> Users linked SOLR-9120 to the root cause as the stack trace is the same , but the fix proposed there won't fix backups to stop failing.
> We need to implement a similar fix in {{SnapShooter#createSnapshot}} to fix the problem
