 ## Run interactive Apache Hive queries
+
 [Apache Hive](https://hive.apache.org) is a data warehouse infrastructure that's built on Hadoop. Hive is used for data summarization, queries, and analysis. You can use Data Lake Tools for Visual Studio to run Hive queries from Visual Studio. For more information about Hive, see [What is Apache Hive and HiveQL on Azure HDInsight?](hdinsight-use-hive.md).
 
 [Interactive Query in Azure HDInsight](../interactive-query/apache-interactive-query-get-started.md) uses [Hive on LLAP](https://cwiki.apache.org/confluence/display/Hive/LLAP) in Apache Hive 2.1. Interactive Query brings interactivity to complex, data warehouse-style queries on large, stored datasets. Running Hive queries on Interactive Query is much faster than traditional Hive batch jobs. 
 
 > [!NOTE]  
 > You can run interactive Hive queries only when you connect to an [HDInsight Interactive Query](../interactive-query/apache-interactive-query-get-started.md) cluster.
