Stefania commented on CASSANDRA-10109:
--------------------------------------

bq. a lister could quite reasonably encounter corruption twice in a row just 
due to tearing of writes

As in a record gets written only partially? I guess I agree in this case.

bq. In which case I think I would prefer to just apply the behaviour we decided 
on for cleanup to listers as well (i.e. ignore the txn log entirely in the 
event it does not validate - but leave that validation logic as is).

OK but if the last record is corrupt at the moment the validation passes. So 
what do we do with this final corrupt record then: is it "UNKNOWN", which means 
transaction always in progress, or do we attempt to at least read the first 
word, the record type, to determine if it is ABORT or COMMIT?

> This traces back to the commit for CASSANDRA-7066 today by [~Stefania] and 
> [~benedict].  Stefania - care to take this ticket and also look further into 
> whether or not we're going to have issues with 7066 on Windows? That error 
> message certainly *sounds* like it's not a good thing.
