This is working fine for Spark 1.4.1 but stopped working for 1.5.0. I think that the problem is that 1.5.0 can now work with different versions of Hive Metastore and probably I need to specify which version I'm using.

via the commandline to spark-submit/spark-shell with --conf; set in spark-defaults, typically in /etc/spark-defaults.conf; can be set in the application, via the SparkContext (or related) objects; Hive¶ Configs can be specified: via the commandline to beeline with --hiveconf; set on the class path in either hive-site.xml or core-site.xml Hive Integration in Spark. From very beginning for spark sql, spark had good integration with hive. 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. spark hive integration 2 | spark hive integration example | spark by akkem sreenivasulu.

Integration with Hive UDFs, UDAFs, and UDTFs. 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 …

Jan 16, 2018 Generic - Issue Resolution For my recent use case I had a requirement to integrate spark2 with hive and then load the hive table from spark, very first solution I found on Google was to move the existing hive-site.xml file to spark conf directory, but this alone would not be sufficient for complete integration and yes i had spent… 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.

Query listener gets event when query is finished, so HMS always gets chance to put entities to Atlas first. 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. This process makes it more efficient and adaptable than a standard JDBC connection from Spark to Hive.

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. Spark SQL supports a different use case than Hive. Compared with Shark and Spark SQL, our approach by design supports all existing Hive features, including Hive QL (and any future extension), and Hive’s integration with authorization, monitoring, auditing, and other operational tools.

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 default configuration uses Hive 1.2.1 with the default warehouse in /user/hive/warehouse. 16/04/09 13:37:54 INFO HiveContext: Initializing execution hive, version 1.2.116/04/09 13:37:58 WARN ObjectStore: Version information not found in Now in HDP 3.0 both spark and hive ha their own meta store.
