-------------------------------------------------------------
Yes, we can create table from existing parquet file and it is a good solution.
but for the request itself, the user want to create table with the schema from
the given parquet file and specify a different location to the table. Maybe
more other table properties.
that's the "create table ... using parquet" cannot achieve.
{code:java}
spark-sql> create table table2 using parquet options(path
'test-data/dec-in-fixed-len.parquet') location '/tmp/table1';
Error in query:
LOCATION and 'path' in OPTIONS are both used to indicate the custom table path,
you can only specify one of them.(line 1, pos 0)
{code}
