Sylvain Lebresne updated CASSANDRA-2279:
----------------------------------------
Attachment: fix-RowIteratorFactory.patch
RowIteration-unit-tests.patch
There was actually 2 related bugs in RowIteratorFactory. Re-attaching new patch
with the 2 unit tests and the fix (fixing both problem and simplifying, I
think, RowIteratorFactory).

> The steps that I took to reproduce it were:
> Create a keyspace, column family, and a key
> Delete the key on Node 1 using the cli (del cf['key'];)
> Flush
> Repair on a cluster with more than 1 node
> Wait GCSeconds
> Compact
> And the empty row would appear on Node 2
> However, when I was able to get rid of the empty rows, I was following these
> steps on a single machine:
> Create a keyspace, column family, and a key
> Delete the key
> Flush
> Sample write (writing to some temporary key)
> Deleting the attribute to that temporary key (not the entire key)
> Flush
> Compact
> or these steps:
> Create a keyspace, column family, and a key
> Delete the key
> Flush
> Wait GCseconds
> Compact
