> In BinaryHashBucketArea.insertToBucket.
> When BinaryHashTable.buildTableFromSpilledPartition."Build in memory hash
> table", it requires memory can put all records, if not, will fail.
> Because the linked hash conflict solution, the required memory calculation
> are not accurate, in this case, we should apply for insufficient memory from
> heap.
> And must be careful, the steal memory should not return to table.
