The HDInsight Hive activity in an Azure Data Factory or Synapse Analytics pipeline executes Hive queries on your own or on-demand HDInsight cluster. This article builds on the data transformation activities article, which presents a general overview of data transformation and the supported transformation activities.
If you are new to Azure Data Factory and Synapse Analytics, read through the introduction articles for Azure Data Factory or Synapse Analytics, and do the Tutorial: transform data before reading this article.
Add an HDInsight Hive activity to a pipeline with UI
To use an HDInsight Hive activity for Azure Data Lake Analytics in a pipeline, complete the following steps:
Search for Hive in the pipeline Activities pane, and drag a Hive activity to the pipeline canvas.
Select the new Hive activity on the canvas if it is not already selected.
Select the HDI Cluster tab to select or create a new linked service to an HDInsight cluster that will be used to execute the Hive activity.
Select the Script tab to select or create a new storage linked service, and a path within the storage location, which will host the script.
