Install LiveData Migrator

Ready to install? Check the prerequisites and then follow these steps to get up and running with LiveData Migrator.

Install LiveData Migrator#

  1. Install LiveData Migrator and upload to your chosen host. If you're migrating from Hadoop Distributed File System (HDFS), install LiveData Migrator on an edge node in the Hadoop cluster. Run the following installation command:

    wget https://wandisco.com/downloads/livedata-migrator.sh
  2. Make the installation script executable and install as the root (or sudo) user. These commands assume that the installer is inside your working directory.

    chmod +x livedata-migrator.sh && ./livedata-migrator.sh
    Known Issue

    On CentOS 6, start the livedata-migrator, hivemigrator, and livedata-ui services manually using the following commands:

    initctl start livedata-migrator; initctl start hivemigrator; initctl start livedata-ui
  3. Check the service statuses with these commands:

    service livedata-migrator status
    service hivemigrator status
    service livedata-ui status

System and custom users for installation#

To run the installer using a default user, run the following command:

./livedata-migrator.sh
ComponentDefault system userDefault system user group
LiveData Migratorhdfshdfs
LiveData UIhdfshdfs

To install the product using a custom user or a custom user group, run the following commands:

Thin installer
./livedata-migrator.sh --user <custom user> --group <custom group>
Fat installer
./livedata-migrator.sh -- --user <custom user> --group <custom group>

This sets the custom user and custom user group for all services and their respective directories.

For more information about configuring custom users, go to Configure system users.

Install LiveData Migrator components on separate hosts#

To install the components on separate hosts, run the following commands:

Install the UI on one host#

./livedata-x.x.x-xx-full_rpm_installer.sh --noexec --keep
cd ui_ldm_hvm
rpm -ivh livedata-ui-<version-number>.noarch.rpm

Install LiveData Migrator, Hive Migrator, and LiveData Migrator CLI on one host#

./livedata-x.xx.x-xx-full_rpm_installer.sh --noexec --keep
cd ui_ldm_hvm
rpm -ivh livedata-migrator-<version-number>.noarch.rpmrpm -ivh hivemigrator-<version-number>.noarch.rpmrpm -ivh livedata-migrator-cli-<version-number>.noarch.rpm
