I do not know of a way to get Impala to read data that it does not
consider a table. Are you concerned about the overhead of Impala's
maintenance of the metadata?

Thank you,
I am currently using this way. But is there any way to load data from hdfs
to parquet table not via external table or internal table?

I think you can follow these two steps in order:
1. Make an external table referring to the CSV
2. Use CREATE TABLE AS SELECT to make a parquet table

Is the data in a format that Impala can read?
