Uninstall Data Migrator

info

An optional step detailed below in the section Uninstall Data Migrator is to delete all Data Migrator directories.
These directories contain user-modified files such as configurations, logs, and backups that you may want to keep.
Archive the directories if you want to keep backups and configurations.

Stop all active migrations​

Before you uninstall Data Migrator, stop all active data and metadata migrations.

  • To stop all data and metadata migrations at once with the UI, go to the Data Migrations or Metadata Migrations page, and select Stop under Bulk Actions.
    See Bulk Actions.

  • To stop all data migrations with the CLI, run the stop all migrations command:

    Example
    migration stop all

  • To stop all metadata migrations with the CLI, run the stop metadata migration command:

    Example
    hive migration stop all

If you have deployed any remote agents (for target metastore connections), sign in to the hosts for the remote agents and uninstall them using the following commands as the root (or sudo) user:

  1. Stop the service (use the initialization system command appropriate for your environment):

    System V
    service hivemigrator-remote-server stop
    systemd

  2. Remove the remote server package:

    Red Hat/CentOS
    yum remove -y hivemigrator-remote-server.noarch
    Ubuntu
    apt-get purge -y hivemigrator-remote-server

  3. Delete all related directories:

    rm -rf /etc/wandisco/hivemigrator-remote-server /var/run/hivemigrator-remote-server
