Description

The TweetParser can only take dataset definition with specific order as follow:

create type Tweet if not exists as open{
id: string,
user: TwitterUser,
latitude:double,
longitude:double,
created_at:string,
message_text:string
};

Different order will cause type cast exception since the order is fixed in code. Also the names of field and number is also fixed, no more or less.

Also Tweet cannot have extra field, and extra field will cause ArrayIndexOutOfBoundsException in IDataParser.writeRecord
