> Some cassandra users use sstable2json and sstablekeys to check -Data and
> -Index files for integrity. For example, if compaction fails, you can find
> out which files are causing the compaction to fail because they're corrupt.
> One type of corruption that can happen in both -Data and -Index files are
> keys getting out of order. (This shouldn't happen, but it can) Cassandra
> catches this error during compaction, but both tools didn't catch it.
> This small patch simply causes an IO Exception during export if it finds out
> of order keys.
> Some further work on it may make this optional with a command-line switch -
> it may be useful to export the data to json even though it's out of order to
> manually play it back, or have another script re-order it.
