Benedict created CASSANDRA-6912:
-----------------------------------
Summary: 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).
