> The exception handling in nextKeyValueTolerateCorruptions treats IOException
> as follows:
> - if EOFException, corrupt, can be tolerated
> - If CheckSumException, corrupt, can be tolerated
> - else not a corruption, re-throw
> But the compression code can also throw IOException in case of corruption,
> which will get re-thrown in this case.
> The correct way of handling IOException is:
> - if BlockMissingException, re-throw.
> - if not BlockMissingException -> corruption, can be tolerated
