> For a MOR table 'mor_simple' and its RO table 'mor_simple_ro' and RT table 'mor_simple_rt', if user drops 'mor_simple_ro' without purging. There might be issue. Reproduce like below:
> {code:java}
> 1. Create table as below:
> CREATE TABLE mor_simple (
>   `id` INT,
>   `name` STRING,
>   `price` DOUBLE)
> USING hudi
> location '/user/hive/warehous/mor_simple'
> OPTIONS(
>   'type' = 'mor',
>   'primaryKey' = 'id',
>   'hoodie.table.precombine.field' = 'id'
> ); 
> 2. Trigger hive-sync by inserting values 
>  insert into mor_simple values (1, 'z3', 1)
> 3. 'show tables' -- we will find mor_simple_rt and mor_simple_ro show up;
> 4. 'drop table mor_simple_ro' and 'show tables' -- we will find mor_simple is dropped but mor_simple_ro can never be dropped.{code}
> We might need to refine DropHoodieTableCommand and take more consideration of identifier of RO/RT.
