    MaxCompute:UDF géospatiales

    Dernière mise à jour :Aug 10, 2026

    Cette rubrique explique comment utiliser les fonctions définies par l'utilisateur (UDF) géospatiales open source pour analyser des données spatiales.

    Prérequis

    Vérifiez que les conditions suivantes sont remplies :

    • Git est installé.

    • Maven est installé et les variables d'environnement sont configurées.

    • Le client MaxCompute est installé.

      Pour plus d'informations sur l'installation du client MaxCompute, consultez la section Installation et configuration du client MaxCompute.

    Contexte

    Apache Hive propose un ensemble d'UDF géospatiales open source. Pour plus d'informations, rendez-vous sur GitHub. MaxCompute permet d'utiliser directement les UDF Hive, y compris les UDF géospatiales Hive.

    Pour savoir comment utiliser les UDF Hive dans MaxCompute, consultez la section Développement d'une UDF en Java.

    Remarque

    En cas de problème lors de l'utilisation des UDF, soumettez-le sur GitHub pour obtenir de l'aide.

    Étape 1 : Préparer une UDF locale

    Préparez une UDF locale en utilisant l'une des méthodes suivantes :

    • Téléchargez le code source et compilez-le dans un package JAR.

      1. Récupérez l'URL de téléchargement du code des UDF géospatiales.

      2. Ouvrez l'outil de ligne de commande Git et téléchargez le package de code des UDF géospatiales pour Hive 2.1.0 sur votre machine locale. Hive 2.1.0 correspond à Hadoop 2.7.2. Exemples de commandes :

        • git clone https://github.com/Esri/spatial-framework-for-hadoop.git
        • git clone -b "v2.1.0" --single-branch git@github.com:Esri/spatial-framework-for-hadoop.git

      3. Créez un projet avec Maven.

        Exemples de commandes :

        cd spatial-framework-for-hadoop
mvn clean package -DskipTests -P java-8,hadoop-2.7,hive-2.1

      4. Copiez le package JAR créé. Ce package JAR contient toutes les méthodes des UDF géospatiales open source.

        Exemple de commande :

        cp hive/target/spatial-sdk-hive-2.1.1-SNAPSHOT.jar ../spatial-sdk-hive.jar

      5. Téléchargez le package JAR dont dépend le projet.

        Exemples de commandes :

        • wget 'https://repo1.maven.org/maven2/com/esri/geometry/esri-geometry-api/2.2.0/esri-geometry-api-2.2.0.jar' -O esri-geometry-api.jar
        • cp ~/.m2/repository/com/esri/geometry/esri-geometry-api/2.2.0/esri-geometry-api-2.2.0.jar ../esri-geometry-api.jar

    • Téléchargez les packages JAR compilés.

      1. Téléchargez le package Spatial JAR et renommez-le en spatial-sdk-hive.jar.

      2. Téléchargez le package Esri Geometry JAR et renommez-le en esri-geometry-api.jar.

      Remarque

      Si le téléchargement des packages échoue, accédez directement au dépôt GitHub correspondant.

    Étape 2 : Enregistrer les UDF auprès de MaxCompute

    1. Exécutez les commandes suivantes sur le client MaxCompute (odpscmd) pour télécharger les deux packages JAR vers le projet en tant que ressources :

      Pour plus d'informations sur l'ajout de ressources, consultez la section Ajout de ressources.

      ADD jar esri-geometry-api.jar;
ADD jar spatial-sdk-hive.jar;

    2. Exécutez les commandes suivantes pour enregistrer les UDF :

    Étape 3 : Tester une UDF

    Soumettez une instruction SQL sur le client MaxCompute pour vérifier le bon fonctionnement d'une UDF. Exemples de commandes :

    --Enable Hive compatibility and submit the test UDF.
SET odps.sql.hive.compatible=true;
SELECT ST_AsText(ST_Point(1, 2));

    Le résultat renvoyé ci-dessous indique que l'UDF est enregistrée auprès de MaxCompute.

    +-----+
| _c0 |
+-----+
| POINT (1 2) |
+-----+

    Pour plus d'informations sur l'utilisation des UDF open source, consultez la documentation des UDF.
