Jonathan Ellis commented on CASSANDRA-1736:
-------------------------------------------
bq. This patch adds the isCompacted method, but it isn't called anywhere
I will remove it.
bq. SSTable.delete() will fail if the SSTable is not marked compacted
If you're referring to
{code}
FileUtils.delete(desc.filenameFor(Component.COMPACTED_MARKER));
{code}
I changed that to not use deleteWithConfirm for exactly that reason.
