> Wrong answer when converting hash to random partition table

>
> for hash partition table, if datalocality is below a threshold, it will be
> treated as random. For now, some partition's datalocality are high, some are
> not, which leads to some partitions are converted to random, some are not.
> But optimizer must treat the whole partition table with the same distribution
> type. So we determine the distribution type of partition table by its first
> partition.
