Drop temporary table by using DROP TABLE XXX...always get "Drop it first before 
removing the permanent table" but I just create a temporary table and have no 
relation with any permanent table. Like the official example :

-- create a word data generator table
CREATE TEMPORARY TABLE word_table (
    word STRING
) WITH (
    'connector' = 'datagen',
    'fields.word.length' = '1'
);

current exception:

So I guess the exception  should append some notice like "please check whether 
miss  a TEMPORARY before TABLE".
