Tyler Hobbs updated CASSANDRA-6912:
-----------------------------------
Since Version: 2.1 beta1
> SSTableReader.isReplaced does not allow for safe resource cleanup
> -----------------------------------------------------------------
>
> Key: CASSANDRA-6912
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6912
> Project: Cassandra
> Issue Type: Bug
> Reporter: Benedict
> Assignee: Benedict
> Fix For: 2.1 beta2
>
>
> There are a number of possible race conditions on resource cleanup from the
> use of cloneWithNewSummarySamplingLevel, because the replacement sstable can
> be itself replaced/obsoleted while the prior sstable is still referenced
> (this is actually quite easy with compaction, but can happen in other
> circumstances less commonly).
