资源中心配置详情

资源中心通常用于上传文件、 UDF 函数，以及任务组管理等操作。针对单机环境可以选择本地文件目录作为上传文件夹（此操作不需要部署 Hadoop）。当然也可以选择上传到 Hadoop or MinIO 集群上，此时则需要有 Hadoop（2.6+）或者 MinIOn 等相关环境。

HDFS 资源配置

当需要使用资源中心进行相关文件的创建或者上传操作时，所有的文件和资源都会被存储在 HDFS 上。所以需要进行以下配置：

配置 common.properties 文件

在 3.0.0-alpha 版本之后，如果需要使用到资源中心的 HDFS 或 S3 上传资源，我们需要对以下路径的进行配置：api-server/conf/common.properties 和 worker-server/conf/common.properties。可参考如下：

注意：

  • 如果只配置了 api-server/conf/common.properties 的文件，则只是开启了资源上传的操作，并不能满足正常使用。如果想要在工作流中执行相关文件则需要额外配置 worker-server/conf/common.properties。
  • 如果用到资源上传的功能，那么安装部署中，部署用户需要有这部分的操作权限。
  • 如果 Hadoop 集群的 NameNode 配置了 HA 的话，需要开启 HDFS 类型的资源上传，同时需要将 Hadoop 集群下的 core-site.xml 和 hdfs-site.xml 复制到 /opt/dolphinscheduler/conf，非 NameNode HA 跳过次步骤。
