> I create a datatype as following:
> {code}
>   create type typeSnapshot if not exists as open {
>       countyID : int32,
>       timeBin: interval,
>       tweetCount: int32,
>       retweetCount: int32,
>       users: [int64],
>       top50HashTags: [{string:int32}]
>     }
> {code}
> It was created successfully. Then I found the *top50HashTags* was wrong. However I can't drop this type due to the following exception:
> {code}
> java.lang.ClassCastException: org.apache.asterix.om.types.AOrderedListType cannot be cast to org.apache.asterix.om.types.ARecordType
