Alexey Zotov updated CASSANDRA-7498:
------------------------------------

    Attachment: CASSANDRA-2.1-7498.txt

I have already created a patch before your comment. 

The patch contains required changes for processing keys in sstable export/import utilities. Regarding backward compatibility, I added an ability to ignore the current key validator type to allow users import previously-generated json files for "non-bytes" keys. For that users need to add -Dskip.key.validator=true parameter during import.

> I examined code of _SSTableImport_ and _SSTableExport_ classes and found one thing that looks strange to me. Currently processing (encoding/decoding) of columns' names and values is performed based on CF Comparator and Value Validator correspondingly. But row keys are processed using _#bytesToHex_ and _#hexToBytes_ methods despite of there is Key Validator. Such approach works properly for "bytes" keys only. For other types it exports keys in a wrong format (i.e. they are exported in unreadable form).
> In the scope of this ticket we need to consider backward compatibility (import of previously exported sstables). For "bytes" keys it will work as previously since _#bytesToHex_ and _#hexToBytes_ methods are used in internals of _BytesType_ class. For other types we need to allow an ability to import data using "bytes" despite of configured validator.
