Ashutosh Mestry updated ATLAS-3902:
-----------------------------------
Description:
*Background*
Consider the scenario where 2 clusters containing Atlas are setup to be
synchronized Atlas' export and import APIs. If the source Atlas has changes
where table is dropped and re-created with same name. The table's entity within
Atlas will get a new GUID but will continue to have the same _qualifiedName_.
This case is handled within the Import API.
However, the case that is not handled is to perform similar update on to the
table's storage descriptor.
*Steps to Duplicate*
# Create a schema within Hive containing database, tables, columns and views.
Atlas will reflect the changes. Perform export. Generate _s1.zip_.
# Drop schema.
# Re-create the same schema within Hive. Perform export. Generate _s2.zip_.
# Clear Atlas database.
# Import _s1.zip_. Observe _application.log_.
# Import s2.zip. Observe _application.log_. During import log will generate
messages like '_GUID Updated: Entity..._'
_Expected result:_ Import should succeed with messages indicating changes
entity's GUID.
_Actual result_: Import fails with errors indicating schema violation
(_AtlasSchemaViolation_)
