Hi,

Yes, it is not needed. Delimiters are need only for text files.

I think that parquet have schema information in its own file.
so you don't need define row separator and column separator in create-table DDL, like that:


total_duration  BigInt)
ROW FORMAT DELIMITED 
  FIELDS TERMINATED BY ',' 
  LINES TERMINATED BY '\n' 



can anyone give me a answer? thanks
