Apache Spark and Apache Hive integration has always been an important use case and continues to be so. 2. Introduction. It leverages Apache Hive LLAP and retrieves data from Hive table into Spark DataFrame.
From spark 2.0, there is no more extra context to create. I read the documentation and observed that without making changes in any configuration file, we can connect spark with hive. Note: I have port-forwarded a machine where hive is running and brought it available to localhost:10000. I even connected the same using presto and was able to run queries on hive. The code is: Set up HMS hook and exposing thrift interface in Hive side; Let Spark session rely on remote HMS via thrift; Please refer below doc (Atlas official doc) to set up Hive hook. https://atlas.apache.org/Hook-Hive.html. If things are not working as expected, you may also want to set up below configuration to hive … For a typical connection, you can use port 10015 to connect to Hive via Spark.

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. To run with YARN mode (either yarn-client or yarn-cluster), link the following jars to HIVE_HOME/lib.
Spark 2.2.1 and Hive 2.3.2 include various bug fixes and improvements.

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. 2017-01-30 · The Databricks platform provides a fully managed Hive Metastore that allows users to share a data catalog across multiple Spark clusters.
Define val sqlContext = new org.apache.spark.sql.hive.HiveContext(sc). But in my opinion the main advantage of Spark is its great integration with Hadoop – you don’t need to invent the bycicle to make the use of Spark if you already have a Hadoop cluster. With Spark you can read data from HDFS and submit jobs under YARN resource manager so that they would share resources with MapReduce jobs running in parallel (which might as well be Hive queries or Pig
