> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.8.0
> Environment: Reproduced on single Cassandra node (CentOS 5.5)
> Reproduced on single Cassandra node (Windows Server 2008)
> Reporter: rene kochen
> Assignee: Sylvain Lebresne
> Fix For: 0.8.1, 0.8.2

> After a minor compaction, deleted key-slices are visible again.
> Steps to reproduce:
> 1) Insert a row named "test".
> 2) Insert 500000 rows. During this step, row "test" is included in a major
> compaction:
> file-1, file-2, file-3 and file-4 compacted to file-5 (includes "test").
> 3) Delete row named "test".
> 4) Insert 500000 rows. During this step, row "test" is included in a minor
> compaction:
> file-6, file-7, file-8 and file-9 compacted to file-10 (should include
> tombstoned "test").
> After step 4, row "test" is live again.
> Test environment:
> Single node with empty database.
> Standard configured super-column-family (I see this behavior with several
> gc_grace settings (big and small values):
> create column family Customers with column_type = 'Super' and comparator =
> 'BytesType;
> In Cassandra 0.7.6 I observe the expected behavior, i.e. after step 4, the
> row is still deleted.
> I've included a .NET program to reproduce the problem. I will add a Java
> version later on.
