Describe the interaction between Hive and HDFS during data storage and retrieval.
- Hive directly accesses HDFS
- Hive loads data into HDFS
- Hive optimizes data in HDFS
- Hive uses HDFS for metadata storage
Hive primarily interacts with HDFS for storing and retrieving data. During query execution, Hive reads data stored in HDFS and processes it according to the query specifications, leveraging HDFS's scalability and reliability. Additionally, Hive can load data into HDFS and optimize data storage formats for efficient querying.
