[jira] [Commented] (CASSANDRA-7498) sstable2json exports keys in a wrong format

Alexey Zotov commented on CASSANDRA-7498:
-----------------------------------------

Jon, 

As I understand from CASSANDRA-7464's discussion new tools will be introduced and the current utilities will be deprecated (and after some time deleted). But since the final design is unclear we cannot say when they will be implemented (I suppose it will take about half a year since it is not minor improvement). Can we include this patch as a fix of the current issue?

> 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.
