Apache Hive storage in public clouds
Knowing the storage locations of Apache Hive data and metadata helps you troubleshoot problems and replicate data.
On public clouds, the Hive warehouse that stores Hive data is located in an object store, such as S3, by default. In the cloud, Hive uses HDFS merely for storing temporary files. The Hive Metastore (HMS) stores the schema for Hive tables. HMS uses a pre-installed MySQL database. You perform little, or no, configuration of HMS in the cloud.
