Now let’s connect to HiveServer2 using !connect and learn how to use embedded and remote modes with examples.. Somewhat ironically, the metastore code currently persists metadata in a relational database (eg Postgres or MySQL), although Hive 2.0 (released 2016) includes support for storing it within an HBase database instead. Metastore server URIs are of the form thrift://host:port, where the port corresponds to the one set by METASTORE_PORT when starting the metastore server. Getting following error while starting HiveMetastore or HiveServer2. In this picture, metastore server code lives inside HS2 JVM instance and metastore server cache is shared within the HiveServer2: On the other hand, Metastore client side lives in client JVM and will go away once the client is gone. Disk storage for the Hive metadata which is separate from. The primary difference between the Hive CLI & Beeline involves how the clients connect to ApacheHive.

Hive security is implemented in HiveServer2, thus Hive shell bypasses any Hive access policies you might have set on specific databases using Ranger or SQL based authorization (only HDFS policies apply in this case). It stores the meta data for Hive tables and relations. For example, Schema and Locations etc. ... if the Metastore Execution Mode is remote, then the file path must match the file path specified by the Hive Metastore Service on the Hadoop cluster. Hives are actually a kind of rash, although not every rash looks like hives. ...
