Hi, [~pauloricardomg] and [~yukim].
Sorry I couldn't reply earlier because I have been with exams during these
weeks and thanks for reviewing the proposal. I agree that it's better to have
first a basic sstabledowngrader than jumping directly to the framework, I have
modified it according to your suggestions. I'll make another change if it's
needed.
Till now I have been looking for inspection tools, I guess I don't have any
problems related with the usage. I'll keep on looking for sstablescrubber tool.
In addition, do you mean with double cycle support that our sstabledowngrader
should work correctly with a flow like "ma" -> "ka" -> "la"?

> Key: CASSANDRA-8928
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8928
> Project: Cassandra
> Issue Type: New Feature
> Components: Tools
> Reporter: Jeremy Hanna
> Priority: Minor
> Labels: gsoc2016, mentor
>
> As mentioned in other places such as CASSANDRA-8047 and in the wild,
> sometimes you need to go back. A downgrade sstables utility would be nice
> for a lot of reasons and I don't know that supporting going back to the
> previous major version format would be too much code since we already support
> reading the previous version.
