>
> Sometimes, auto map join conversion unexpectedly fails to choose map join
> over a common join, even if the auto map join conversion's size criterion is
> satisfied.
> This is caused by an integer overflow bug in the method {{compareTo}} of the
> class {{ConditionalResolverCommonJoin.AliasFileSizePair}}.
> The bug is triggered only if the big table size exceeds the small table size
> by at least 2**31 bytes.
