> NoSuchFileException when removing a snapshot
> ---------------------------------------------
>
> Key: CASSANDRA-18211
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18211
> Project: Cassandra
> Issue Type: Bug
> Components: Local/Snapshots
> Reporter: Jacek Lewandowski
> Assignee: Stefan Miklosovic
> Priority: Normal
> Fix For: 4.1.x, 4.x
>
>
> Automatic deletion of expired snapshots maintained by {{SnapshotManager}} can
> race with manual snapshot removal in a way an exception like
> {{NoSuchFileException}} is thrown.
> It is because the snapshot directory existence is checked and deleted if it
> exists as a non-atomic operation. Since we can potentially have two threads
> attempting to do that at the same time (automatic and manual snapshot
> removal) it may lead to a race in rare situations.
