How does presto read local files in parquet format

[jiangjiguang]

presto has the "Local File Connector" , but maybe it only reads http_request_log.

I do not know how to read l local file in parquet format

@jiangjiguang there is an undocumented hive connector feature where you can set the following config and use a local directory as the catalog.

hive.metastore=file
hive.metastore.catalog.dir=file:/mnt/hive_data/

Now, you have to create a table say customer using the parquet file schema.
You will see a folder with this table name /mnt/hive_data/customer
Then move your parquet file to this folder. You should be able to query the Parquet file.

We should also have a formal way in Presto to read local Parquet/ORC files. I will look into formalizing the hive.metastore=file.
