将S3用于HIVE元存储库？
[英]Use S3 for HIVE metastore?
问题描述
I'm configuring S3 to be a data warehouse for Hive. 
我将S3配置为Hive的数据仓库。 However, I'm not sure if the 'metastore' part of Hive can use S3 as a storage or not. 但是，我不确定Hive的“元存储”部分是否可以使用S3作为存储。
Most tutorials (ie https://data-flair.training/blogs/apache-hive-metastore/ ) mention that the metastore only supports Derby and a few other RDBMS. 大多数教程（即https://data-flair.training/blogs/apache-hive-metastore/ ）都提到元存储仅支持Derby和其他一些RDBMS。
Is that true? 真的吗？ Configuring metastore to use s3 as storage sounds like a simple config change to me. 配置metastore以将s3用作存储听起来对我来说是一个简单的配置更改。

The Hive Metastore persists the metadata for Hive tables and partitions. Hive Metastore保留Hive表和分区的元数据。 It is backed by a relational database, and currently MySQL, Postgres, Oracle, and MS SQL Server are supported. 它由关系数据库支持，目前支持MySQL，Postgres，Oracle和MS SQL Server 。 S3 is an object store , not a relational database. S3是对象存储 ，而不是关系数据库。
