11 Jan 2018 If we are using earleir Spark versions, we have to use HiveContext which is variant of Spark SQL that integrates with data stored in Hive.

Hive Tables. Specifying storage format for Hive tables; Interacting with Different Versions of Hive Metastore. Spark SQL also supports reading and writing data 

One of the most important pieces of Spark SQL’s Hive support is interaction with Hive metastore, which enables Spark SQL to access metadata of Hive tables. Starting from Spark 1.4.0, a single binary build of Spark SQL can be used to query different versions of Hive metastores, using the configuration described below. I have Spark+Hive job that is working fine. I'm trying to configure the environment for local development and integration testing: Docker images to bootstrap Hive Server, metastore, etc Docker image Spark Hire partners and integrates with the world’s leading applicant tracking systems to empower more efficient customer workflows.

You integrate Spark-SQL with Hive when you want to run Spark-SQL queries on Hive tables. This information is for Spark 2.0.1 or later users. Integrate Spark-SQL (Spark 1.6.1) with Hive. You integrate Spark-SQL with Hive when you want to run Spark-SQL queries on Hive tables.

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.

SAP HANA is expanding its Big Data solution by providing integration to Apache Spark using the HANA smart data access technology. 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. Execution: UDFs, UDAFs, SerDes, HiveConf and various helper functions for configuration.

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. 1.4 Other Considerations It works well and I can do queries and inserts through hive. IF I try a query with a condition by the hash_key in Hive, I get the results in seconds. But doing the same query through spark-submit using SparkSQL and enableHiveSupport (accesing Hive) it doesn't finish.It seems that from Spark it's doing a full scan to the table.

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. Get following details from hive for spark or try this HWC Quick Test Script A Hive metastore warehouse (aka spark-warehouse) is the directory where Spark SQL persists tables whereas a Hive metastore (aka metastore_db) is a relational database to manage the metadata of the persistent relational entities, e.g.

Spark streaming will read the polling stream from the custom sink created by flume. Spark streaming app will parse the data as flume events separating the headers from the tweets in json format. Once spark has parsed the flume events the data would be stored on hdfs presumably a hive warehouse. Hive Integration.

In HDInsight 4.0, Spark and Hive use independent catalogs for accessing SparkSQL or Hive tables. A table created by Spark lives in the Spark catalog. A table created by Hive lives in the Hive catalog.

Tags spark rdd. Developer on Alibaba Coud: Build your first Spark on hive 与 Hive on Spark 的区别. Spark on hive; Spark通过Spark-SQL使用hive 语句,操作hive,底层运行的还是 spark rdd。 （1）就是通过sparksql，加载hive的配置文件，获取到hive的元数据信息 （2）spark sql获取到hive的元数据信息之后就可以拿到hive的所有表的数据 （3）接下来就 In this post, we will look at how to build data pipeline to load input files (XML) from a local file system into HDFS, process it using Spark, and load the data into Hive. We'll briefly start by going over our use case: ingesting energy data and running an Apache Spark job as part of the flow.
