Data Migrator jar

If you want to try out Data Migrator using a quick method, use the livedata-migrator.jar. This is an alternative to using the system service and it does not require configuration.


Use the system service instead for production deployment as it allows you to maintain long-lived migrations, have a common configuration that survives service restarts, and retain logging information in a central directory.

On the Data Migrator host, follow the steps below to run the jar:

  1. Switch to the Hadoop Distributed File System (HDFS) superuser.
    su - hdfs
  2. Change to the directory where the jar is located:
    cd /opt/wandisco/livedata-migrator
  3. Run the jar file to access the action prompt.
    • If Kerberos is disabled in your environment, run:
