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。
  • 资源中心可以对接分布式的文件存储系统，如Hadoop（2.6+）或者MinIO集群，也可以对接远端的对象存储，如AWS S3或者阿里云 OSS，华为云 OBS 等。
  • 资源中心也可以直接对接本地文件系统。在单机模式下，您无需依赖Hadoop或S3一类的外部存储系统，可以方便地对接本地文件系统进行体验。
  • 除此之外，对于集群模式下的部署，您可以通过使用S3FS-FUSE将S3挂载到本地，或者使用JINDO-FUSE将OSS挂载到本地等，再用资源中心对接本地文件系统方式来操作远端对象存储中的文件。

对接本地文件系统

配置 common.properties 文件

Dolphinscheduler 资源中心使用本地系统默认是开启的，不需要用户做任何额外的配置，但是当用户需要对默认配置做修改时，请确保同时完成下面的修改。

  • 如果您以 集群 模式或者 伪集群 模式部署DolphinScheduler，您需要对以下路径的文件进行配置：api-server/conf/common.properties 和 worker-server/conf/common.properties；
  • 若您以 单机 模式部署DolphinScheduler，您只需要配置 standalone-server/conf/common.properties，具体配置如下：

您可能需要涉及如下的修改：

  • 将 resource.storage.upload.base.path 改为本地存储路径，请确保部署 DolphinScheduler 的用户拥有读写权限，例如：resource.storage.upload.base.path=/tmp/dolphinscheduler。当路径不存在时会自动创建文件夹

注意

  1. LOCAL模式不支持分布式模式读写，意味着上传的资源只能在一台机器上使用，除非使用共享文件挂载点
  2. 如果您不想用默认值作为资源中心的基础路径，请修改resource.storage.upload.base.path的值。
  3. 当配置 resource.storage.type=LOCAL，其实您配置了两个配置项，分别是 resource.storage.type=HDFS 和 resource.hdfs.fs.defaultFS=file:/// ，我们单独配置 resource.storage.type=LOCAL 这个值是为了 方便用户，并且能使得本地资源中心默认开启

对接AWS S3

如果需要使用到资源中心的 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：

配置以下字段

......

resource.storage.type=S3

......

resource.aws.access.key.id=aws_access_key_id
# The AWS secret access key. if resource.storage.type=S3 or use EMR-Task, This configuration is required
resource.aws.secret.access.key=aws_secret_access_key
# The AWS Region to use. if resource.storage.type=S3 or use EMR-Task, This configuration is required
resource.aws.region=us-west-2
# The name of the bucket. You need to create them by yourself. Otherwise, the system cannot start. All buckets in Amazon S3 share a single namespace; ensure the bucket is given a unique name.
resource.aws.s3.bucket.name=dolphinscheduler
# You need to set this parameter when private cloud s4. If S3 uses public cloud, you only need to set resource.aws.region or set to the endpoint of a public cloud such as S3.cn-north-1.amazonaws.com.cn
resource.aws.s3.endpoint=

......

对接分布式或远端对象存储

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分布式文件系统HDFS或者远端的对象存储，如S3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 worker-server/conf 以及 api-server/conf，非 NameNode HA 跳过次步骤。
