In current cte multicast fragment param computing logic in coordinator, if shared hash table for bc opened, its destination's number will be the same as be hosts'. But the judgment of falling into shared hash table bc part code is wrong, which will cause when a multicast's target is fixed with both bc and partition, the first bc info will overwrite the following partition's, i.e, the destination info will be the host level, which should be per instance. This will cause the hash partition part hang.
