Subject [jira] [Commented] (CASSANDRA-10377) AssertionError: attempted to delete non-existing file CommitLog
Date Wed, 14 Oct 2015 16:59:06 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14957270#comment-14957270
] 

Robert Stupp commented on CASSANDRA-10377:
------------------------------------------

[~vovodroid] & [~blambov], can you take a look at the 2.1 branch? It uses the same approach,
but is a bit different as this piece of code changed between 2.1 and 2.2.

> I added some logs to *deleteWithConfirm* and it showed that this file really was deleted
by previous delete action, i.e. it was second attempt to delete the same log. Commit log with
next number exists in the same time, so log was switched.
> I disabled assert and it seems to have no no bad effect.
