Configure the UI

Find details here for the configuration properties of the UI. Properties are defined in the following file:


When adding new properties or changing existing values, restart the Data Migrator service.

General configuration

Configure how the UI is run overall.

server.portSet the port on which the UI will be available. This is overridden by the server.ssl.port when TLS is enabled.

Default value: 8081
Allowed values: An integer value between 1024 and 65535

UI logging

The UI configuration file (/etc/wandisco/ui/ contains the following logging configuration properties:

logging.output.pathThe output path for all logging.

Default value: /var/log/wandisco/ui
Allowed values: The full path to a valid directory that is writable by the user running the UI. The user is typically hdfs.
logging.level.ROOTThe log level.

Default value: INFO
Allowed values: A valid log level: TRACE, DEBUG, INFO, WARN, ERROR, FATAL, or OFF.
logging.audit.output.filenameThe output filename for the audit log. This will be suffixed with the date in YYYY-MM-DD format.

Default value: livedata_ui_audit
Allowed values: A valid string.
logging.audit.days-keptThe amount of days that the audit log will be retained.

Default value: 90
Allowed values: An integer value for the number of days that logs are kept.

Configure the log output path for the UI

  1. Open /etc/wandisco/ui/
  2. Edit the following line, replacing the default path /var/log/wandisco/ui with your own. For example:
  3. Save the change.
  4. Restart Data Migrator.

Reset admin user password

Reset the admin user's password for Data Migrator by creating a file named reset.password in the UI configuration directory (/etc/wandisco/ui/ by default).

Add the existing email value and a new password value in the file (The password must conform to the same password requirements as the UI) :

Restart the UI server after the file has been created. When the UI restarts, it updates the password to the value entered in the file, the file is then automatically deleted.


This process cannot be used for users other than the admin. It does not work for the admin user's email address, which cannot be changed.


Basic authentication compatibility

If basic authentication is enabled on Data Migrator or Hive Migrator (or both), the following additional steps are required to maintain UI functionality: Update basic auth in the UI.


Configure how the UI uses TLS, which is disabled by default.

server.ssl.enabledSet to true to enable TLS. If no other TLS values are set, this will use an internal keystore and a self-signed certificate to serve the UI.

Default value: false
Allowed values: true, false
server.ssl.portSet the port on which the UI should be available when TLS is enabled.

Default value: 8443
Allowed values: An integer value between 1024 and 65535
server.ssl.key-storeThe path to the key store which should be used instead of the internal default
server.ssl.key-store-passwordThe password to be used to access the key store
server.ssl.key-aliasThe alias of the certificate to be used
server.ssl.key-store-typeOptional: set the key store type. Defaults to PKCS12
application.liveMigratorV2.client.noCheckCertificateOptional: add this property and set the value to true if you want to implicitly trust certificates from remote Data Migrator instances.
Default value: false

Instead of using this property, we recommend that you import your server certificate into a truststore.

The example command below will import a certificate file, certificate-file.crt into the Java truststore cacerts:

keytool -importcert -file /etc/wandisco/certificate-file.crt -keystore cacerts -alias key-alias

For more information about parameters, see Oracle's documentation.

Using a custom truststore (UI)

The default SSL keystore configuration for the UI is stored in /etc/wandisco/ui/


If you define a custom keystore using these configuration parameters, the truststore will still default to the one in the JAVA home directory.

For more information, see Transport Layer Security (TLS).

Use the following steps to enter a custom truststore:

  1. Open /etc/wandisco/ui/vars.env in a text editor.
  2. Add the following line:
    This UI extra JAVA argument adds the following:
  • - Path to the custom truststore file.
  • - The custom truststore password.
  1. Save the change.
  2. Restart the UI service. using the command:
    systemctl restart livedata-ui

Data Migrator instance

Default Data Migrator instance hostname and port /etc/wandisco/ui/


Directory structure

The following directories are used for the UI:

/etc/wandisco/uiConfiguration files
/opt/wandisco/uiOperation files
/var/run/livedata-uiRuntime files
