Databricks provides a managed Apache Spark platform to simplify running production applications, real-time data exploration, and infrastructure complexity. A key piece of the infrastructure is the Apache Hive Metastore, which acts as a data catalog that abstracts away the schema and table properties to allow users to quickly access the data.

From very beginning for spark sql, spark had good integration with hive. 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. It integrates directly with the spark session.

Spark SQL supports Analyze only works for Hive tables, but dafa is a LogicalRelation at org.apache.spark.sql.hive.HiveContext.analyze 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. 2018-01-19 · To work with Hive, we have to instantiate SparkSession with Hive support, including connectivity to a persistent Hive metastore, support for Hive serdes, and Hive user-defined functions if we are using Spark 2.0.0 and later. If we are using earlier Spark versions, we have to use HiveContext which is variant of Spark SQL that integrates […] Spark HWC integration - HDP 3 Secure cluster Prerequisites : Kerberized Cluster. Enable hive interactive server in hive.

Spark SQL supports integration of Hive UDFs, UDAFs, and UDTFs. Similar to Spark UDFs and UDAFs, Hive UDFs work on a single row as input and generate a single row as output, while Hive UDAFs operate on multiple rows and return a single aggregated row as a result. In addition, Hive also supports UDTFs (User Defined Tabular Functions) that act on

The basic use case is the ability to use Hadoop as a cold data store for less frequently accessed data. Right now Spark SQL is very coupled to a specific version of Hive for two primary reasons. Metadata: we use the Hive Metastore client to retrieve information about tables in a metastore.

Now in HDP 3.0 both spark and hive ha their own meta store. Hive uses the "hive" catalog, and Spark uses the "spark" catalog. With HDP 3.0 in Ambari you can find below configuration for spark. As we know before we could access hive table in spark using HiveContext/SparkSession but now in HDP 3.0 we can access hive using Hive Warehouse Connector.

Name : hive.metastore.event.listeners Value : org.apache.atlas.hive.hook.HiveMetastoreHook Is it safe to assume that all dependent hive entities are created before spark_process and we do won't run in any race conditions? Query listener gets event when query is finished, so … Spark - Hive Integration failure (Runtime Exception due to version incompatibility) After Spark-Hive integration, accessing Spark SQL throws exception due to older version of Hive jars (Hive 1.2) bundled with Spark.
