Hive for Parquet files

The catalog type hive-hadoop2 is used to access Parquet datasets stored in any Object Storage. These Parquet datasets are mapped to Hive tables in a Metastore, that can be the Embedded Hive Metastore or any External Metastore.

hive.properties
connector.name=hive-hadoop2

# Embedded Hive Metastore
hive.metastore.uri=thrift://hive-metastore:9083

To query Parquet datasets you have to create Hive tables in the Denodo Embedded MPP. You can use the embedded data source in Denodo to graphically explore Parquet datasets (including those using the Hive style partitioning), create tables and base views in Denodo.
