+# Apache Zeppelin
+
+## Overview
+
+Use `Zeppelin Task` to create a zeppelin-type task and execute zeppelin notebook paragraphs. When the worker executes `Zeppelin Task`,
+it will call `Zeppelin Client API` to trigger zeppelin notebook paragraph. Click [here](https://zeppelin.apache.org/) for details about `Apache Zeppelin Notebook`. 
+
+## Create Task
+
+- Click Project Management-Project Name-Workflow Definition, and click the "Create Workflow" button to enter the DAG editing page.
+- Drag <img src="/img/tasks/icons/zeppelin.png" width="15"/> from the toolbar to the canvas.
+
+## Task Parameter
+
+- Node name: The node name in a workflow definition is unique.
+- Run flag: Identifies whether this node can be scheduled normally, if it does not need to be executed, you can turn on the prohibition switch.
+- Descriptive information: Describe the function of the node.
+- Task priority: When the number of worker threads is insufficient, execute in the order of priority from high to low, and tasks with the same priority will execute in a first-in first-out order.
+- Worker grouping: Assign tasks to the machines of the worker group to execute. If `Default` is selected, randomly select a worker machine for execution.
+- Number of failed retry attempts: The failure task resubmitting times. It supports drop-down and hand-filling.
+- Failed retry interval: The time interval for resubmitting the task after a failed task. It supports drop-down and hand-filling.
+- Timeout alarm: Check the timeout alarm and timeout failure. When the task exceeds the "timeout period", an alarm email will send and the task execution will fail.
+- Zeppelin Note ID: The unique note id for a zeppelin notebook note.
+- Zeppelin Paragraph ID: The unique paragraph id for a zeppelin notebook paragraph.
