Prerequisites

  • Install the correct version of Apache Spark. Exporting data from different sources requires different Spark versions. For more information, see Software dependencies.

Steps

  1. Clone the repository nebula-exchange in the / directory.

  2. Switch to the directory nebula-exchange.

    cd nebula-exchange

  3. Package NebulaGraph Exchange. Run the following command based on the Spark version:

    • For Spark 2.2：

      mvn clean package -Dmaven.test.skip=true -Dgpg.skip -Dmaven.javadoc.skip=true \
-pl nebula-exchange_spark_2.2 -am -Pscala-2.11 -Pspark-2.2

    • For Spark 2.4：

      mvn clean package -Dmaven.test.skip=true -Dgpg.skip -Dmaven.javadoc.skip=true \
-pl nebula-exchange_spark_2.4 -am -Pscala-2.11 -Pspark-2.4

    • For Spark 3.0：

      mvn clean package -Dmaven.test.skip=true -Dgpg.skip -Dmaven.javadoc.skip=true \
-pl nebula-exchange_spark_3.0 -am -Pscala-2.12 -Pspark-3.0

After the compilation is successful, you can find the nebula-exchange_spark_x.x-release-3.6.jar file in the nebula-exchange_spark_x.x/target/ directory. x.x indicates the Spark version, for example, 2.4.
