TopicAdd file reader plugin for DolphinScheduler Python API label
DescriptionCurrently, DolphinScheduler Python API only could pass string format arg as tasks' parameter, such as our tutorial we only pass a string to shell task type. But generally, users hope the command is stored in other resources(for easier maintenance and integration), such as local file systems, GitHub, GitLab, Amazon S3, Aliyun OSS and etc. Maybe we could add trick like
@Resource(
type="github",
id="https://github.com/apache/dolphinscheduler/tree/dev/script"
)
with ProcessDefinition(
name="tutorial",
schedule="0 0 0 * * ? *",
start_time="2021-01-01",
tenant="tenant_exists",
) as pd:
task_parent = Shell(name="task_parent", command="install.sh")
task_child_one = Shell(name="task_child_one", command="start-all.sh'")
task_child_two = Shell(name="task_child_two", command="stop-all.sh")
task_union = Shell(name="task_union", command="status-all.sh")And task task_parent will load file content from URL https://github.com/apache/dolphinscheduler/blob/dev/script/install.sh and pass it to parameter Output Standard
Requirements
What Can You LearnWe wish everyone joining SoC could learn some things from the project. When you finish this project, you could learn:
课题为 DolphinScheduler Python API 添加资源文件加载插件 标签
描述目前，DolphinScheduler Python API 只能传递字符串格式传递任务的参数，例如我们的 tutorial 我们只将一个字符串传递给 shell 任务类型。但通常来说，用户希望具体的执行代码储存在其他系统中（希望更好维护和集成），例如将具体文件存储在本地文件系统、GitHub、GitLab、Amazon S3、阿里云 OSS 等。也许我们可以添加语法糖让用户更加简单的操作外部文件

Topicdetect and store all of application ids of yarn jobs automatically, instead of extracting them in task logs with a regexp Label
DescriptionDolphinScheduler support a wide spectrum of tasks, such as python, shell, etc. A basic function is to collect and kill all of the yarn jobs submitted by these tasks. Output Standard
Requirements
What Can You LearnWe wish everyone joining SoC could learn some things from the project. When you finish this project, you could learn Yarn, Hive, Spark SQL, Aspect-Oriented Programming 课题自动收集、保存作业提交的Yarn作业的application id 标签
描述DolphinScheduler支持各种各样的作业，比如Python、Shell等，其中一个很基础的功能就是收集这些作业创建的Yarn Job的application id。现在的实现方式是用一个正则表达式从作业的日志中解析，但这并不是一个完美的实现方式，本课题的任务就是用一种新的方式去自动收集、报错Yarn Job的application id信息，当然了，必须对用户透明，即对用户创建的作业无侵入。 产出
