Known issues

This article describes the limitations and known issues of LiveData Migrator for Azure.

LiveData Migrator target service principal​

When you select the Create New option when selecting a service principal in the Azure Portal, you aren't offered an option to assign it the necessary storage blob owner permissions. As a result, operations with the filesystem will fail due to insufficient permissions.

We recommend you follow these steps instead:

  • Manually create the service principal on your Hadoop filesystem.
  • Assign it the correct permissions.
  • Select Choose Existing in the Azure Portal.
  • Choose your service principal in the list.

Glob pattern exclusions are not reported if added after the initial scan​

If you add glob pattern exclusions after the initial scan, they don't appear in the metrics, which will incorrectly report no new file exclusions.

  • All files are excluded correctly. The issue only affects reporting.
  • This issue only applies to glob pattern exclusions. File size-based exclusions are not affected.

There's no need for a workaround, as there's no impact on migrations. Files are correctly excluded.
