Hive is a distributed database, and Spark is a framework for data analytics. One query on spark structured streaming integration with HIVE table. I have tried to do some examples of spark structured streaming. here is my example val spark =SparkSession.builder().appName(" Spark connects to the Hive metastore directly via a HiveContext. It does not (nor should, in my opinion) use JDBC. First, you must compile Spark with Hive support, then you need to explicitly call enableHiveSupport() on the SparkSession bulider. Additionally, Spark2 will need you to provide either .

Note: If you installed Spark with the MapR Installer, the following steps are not required. Apache Hive supports analysis of large datasets stored in Hadoop’s HDFS and compatible file systems such as Amazon S3 filesystem. It provides an SQL-like language called HiveQL with schema on read and transparently converts queries to Hadoop MapReduce, Apache Tez and Apache Spark jobs. To add the Spark dependency to Hive: Prior to Hive 2.2.0, link the spark-assembly jar to HIVE_HOME/lib. Since Hive 2.2.0, Hive on Spark runs with Spark 2.0.0 and above, which doesn't have an assembly jar.

Hive was primarily used for the sql parsing in 1.3 and for metastore and catalog API’s in later versions. In spark 1.x, we needed to use HiveContext for accessing HiveQL and the hive metastore. From spark 2.0, there is no more extra context to create.

If backward compatibility is guaranteed by Hive versioning, we can always use a lower version Hive metastore client to communicate with the higher version Hive metastore server. For example, Spark 3.0 was released with a builtin Hive client (2.3.7), so, ideally, the version of server should >= 2.3.x.

The Hive Warehouse Connector makes it easier to use Spark and Hive together. The HWC library loads data from LLAP daemons to Spark executors in parallel.
