Piotr Kołaczkowski updated CASSANDRA-4049:
------------------------------------------
Attachment: 4049-v4.txt
[~jbellis] Looks and works good.
I added a guard against adding the same component more than once (just a
cosmetic thing to avoid duplicate TOC entries, because components is a set
anyway). Attached as 4049-v4.txt.
You can go on and merge it into 1.1.7.

> CFS compaction strategy coming up in the next DSE release needs to store some
> important information in Tombstones.db and RemovedKeys.db files, one per
> sstable. However, currently Cassandra issues warnings when these files are
> found in the data directory. Additionally, when switched to
> SizeTieredCompactionStrategy, the files are left in the data directory after
> compaction.
> The attached patch adds new components to the Component class so Cassandra
> knows about those files.
