Description

When there's no data in Hive table or in incremental query result set, the #3 "Step Name: Build Dimension Dictionary" will fail due to zero record.
Error and block job is not ideal solution since many cases require empty segments to be created as placeholder for further refresh and merge, and continue to build with future data.

Requirement:
Add checkpoint about empty result set and continue entire cube build job.
