----------------------------------------
Assignee: Gary Dusbabek
> failed compactions should not leave tmp files behind
> ----------------------------------------------------
>
> Key: CASSANDRA-1596
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1596
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Peter Schuller
> Assignee: Gary Dusbabek
> Priority: Minor
>
> Using a somewhat old (few months) trunk running tests, I had a compaction
> failure due to the 2 TB file size limit on ext3fs. The tmp file was left
> behind, after which further compaction proceeded.
> This can be detrimental in particular because disk space requirements can
> increase, having additional partially written but abandoned compacted
> sstables around.
> Stack trace with code path included below.
> I can imagine that for debugging purposes there would be cases where you do
> not want a compaction to immediately remove the temp file. On the other hand,
> compaction failures would presumably be caused by the input most of the time,
> rather than the output. So the extra effort of having to patch cassandra to
> avoid the removal does not seem like a critical issue. Maybe one can provide
> a JMX tunable to turn off removal if this is a concern. Thoughts?
