Running the Hive client with DSE Hadoop (deprecated)
Steps to start a Hive client with DSE Hadoop.
Hadoop is deprecated for use with DataStax Enterprise. DSE Hadoop and BYOH (Bring Your Own Hadoop) are deprecated. Hive is also deprecated and will be removed when Hadoop is removed.
With DSE Hadoop, you can run Hive as a
server or as a client. DataStax Enterprise supports Apache HiveServer and
Apache HiveServer2:
- HiveServer is an optional service for remote clients to submit programmatic requests to Hive.
- HiveServer2 is an improved version of HiveServer that supports multi-client concurrency and other features. You can use the Beeline command shell with HiveServer2.
Use a Hive client on a node in the cluster under these conditions:
- To connect to the Hive server running on another node
- To use Hive in a single-node cluster
Start a Hive client
You can start a Hive client on any analytics node and run MapReduce queries directly on data already stored in Cassandra. You run Hive as a client to perform the examples in this document.
