Answer 1

Hey,

The metastore stores the schema and partition information of Hive tables. A relational database is used as metastore.

There are three modes of Hive metastrore deployment:

• Embedded Metastore:- By default in hive, metastore services runs on the same JVM as Hive services.
• Local Metastore:- Here metastore service still runs in the same JVM as Hive but it connects to a database running in a separate process either on same machine or on a remote machine.
• Remote Metastore:- Metastore runs in its own separate JVM not on hive service JVM.
