What are the different ways to import data into a hive?
Data can be imported into Hive in several different ways:
- By using the INSERT INTO statement, you can copy data from one table to another, or insert data into a table.
- You can load data files from an HDFS path into a table using the LOAD DATA INPATH statement.
- By using the INSERT OVERWRITE DIRECTORY statement, the query results can be written directly to an HDFS path.
- With external tables, you can create tables that directly point to data files in HDFS without needing to copy the data to the Hive warehouse.
- Using Sqoop or other tools: Data can be imported from relational databases or other data storage systems into Hive using tools such as Sqoop.
