OpenSearch Hadoop

OpenSearch real-time search and analytics natively integrated with Hadoop. Supports Map/Reduce, Apache Hive, Apache Spark.


OpenSearch (1.3.x or higher) cluster accessible through REST. That's it! If using SigV4 IAM auth features, you would need to include the aws-sdk-bundle in your job classpath.


Please see the USER_GUIDE for usage.


See Compatibility.

Building the source

OpenSearch Hadoop uses Gradle for its build system and it is not required to have it installed on your machine. By default (gradlew), it automatically builds the package and runs the unit tests. For integration testing, use the integrationTests task. See gradlew tasks for more information.

To create a distributable zip, run gradlew distZip from the command line; once completed you will find the jar in build/libs.

To build the project, JVM 8, JVM 11, and JVM 17 are required. The minimum compiler version is Java 14 and the minimum runtime is Java 8.
