Instructions for using the Dolphin Scheduler's Ambari plug-in

Note

  1. This document is intended for users with a basic understanding of Ambari
  2. This document is a description of adding the Dolphin Scheduler(version 1.3.0) service to the installed Ambari service

Installation preparation

  1. Prepare the RPM packages

    • It is generated by executing the command mvn -U clean install -Prpmbuild -Dmaven.test.skip=true -X in the project root directory (In the directory: dolphinscheduler-dist/target/rpm/apache-dolphinscheduler-incubating/RPMS/noarch )
  2. Create an installation for DS,who have read and write access to the installation directory (/opt/soft)

  3. Install with rpm package

    • Manual installation (recommended):
      • Copy the prepared RPM packages to each node of the cluster
      • Execute with DS installation user: rpm -ivh apache-dolphinscheduler-incubating-xxx.noarch.rpm
    • Automatic installation with ambari
      • Each node of the cluster needs to configure the local yum source
      • Copy the prepared RPM packages to each node local yum source
  4. Copy plug-in directory

    • copy directory ambari_plugin/common-services/DOLPHIN to ambari-server/resources/common-services/
    • copy directory ambari_plugin/statcks/DOLPHIN to ambari-server/resources/stacks/HDP/2.6/services/--stack version is selected based on the actual situation
  5. Initializes the database information

    -- Create the database for the Dolphin Scheduler:dolphinscheduler
    CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE
    utf8_general_ci;
    
    -- Initialize the user and password for the dolphinscheduler database and assign permissions
    -- Replace the {user} in the SQL statement below with the user of the dolphinscheduler database
    GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'%' IDENTIFIED BY '{password}';
    GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'localhost' IDENTIFIED BY
    '{password}';
    flush privileges;
    

Ambari Install Dolphin Scheduler

  1. Install Dolphin Scheduler on ambari web interface

  2. Select the nodes for the Dolphin Scheduler's Master installation

  3. Configure the Dolphin Scheduler's nodes for Worker, Api, Logger, Alert installation

  4. Set the installation users of the Dolphin Scheduler service (created in step 1) and the user groups they belong to

  5. Configure the database information (same as in the initialization database in step 1)

  6. Configure additional information if needed

  7. Perform the next steps as normal

  8. The interface after successful installation


Add components to the node through Ambari -- for example, add a DS Worker

NOTE: DS Logger is the installation dependent component of DS Worker in Dolphin's Ambari installation (need to add installation first; Prevent the Job log on the corresponding Worker from being checked)

  1. Locate the component node to add -- for example, node ark3

    DS2_AMBARI_011

  2. Add components -- the drop-down list is all addable

    DS2_AMBARI_012

  3. Confirm component addition

    DS2_AMBARI_013

  4. After adding DS Worker and DS Logger components

    DS2_AMBARI_015

  5. Start the component

    DS2_AMBARI_016

Remove the component from the node with Ambari

  1. Stop the component in the corresponding node

    DS2_AMBARI_018

  2. Remove components

    DS2_AMBARI_019
