- Update the algorithm for creating views that depend on other views.
- Add check for successful execution of the "hadoop distcp" command.
- Add a check for successful copy operation of all entities.
- Upon facing an error in a DB, exit the method, instead of the whole script.
- Improve logging.
- Code polishing.
- Use only hive commands in the Ocean Cluster, as the "impala-shell" will be removed from there to free-up resources.
- Hugely improve the performance in every aspect of the copying process: a) speedup file-transferring and DB-deletion, b) eliminate permissions-assignment, "load" operations and "use $db" queries, c) retry only the "create view" statements and only as long as they depend on other non-created views, instead of trying to recreate all tables and views 5 consecutive times.
- Add error-checks for the creation of tables and views.
- Drop table statements for all tables to avoid duplicates in case of wf rerun
- Add pdfsaggregated step to create the indi_is_result_accessible table. This step is executed on the new impala cluster only, since the pdfaggregation_i is updated on this cluster.
1. Remove tables/views from old databases in the new cluster, before dropping the dbs
2. Fix id in result_accessroute, indi_impact_measures, indi_pub_bronze_oa
1. Remove external table definitions in stats_ext
2. Fix the issue where some views are not created.
3. Added two workflow parameters for copying also the usage stats dbs
