             Summary: Update Classification: Does Not Update modificationTimestamp
                 Key: ATLAS-2805
                 URL: https://issues.apache.org/jira/browse/ATLAS-2805
             Project: Atlas
          Issue Type: Bug
          Components:  atlas-core
    Affects Versions: 0.8.3
            Reporter: Ashutosh Mestry
            Assignee: Ashutosh Mestry
             Fix For: 0.8.3


*Background*

Existing implementation of _EntityGraphMapper_._addClassifications_ does not update _modificationTimestamp_. 

This causes inconsistency if entities are fetched using _modificationTimestamp_. 

*Steps* *to Duplicate*

_Pre-requisites_: Setup an instance with few entities. Create classifications, say _PII_. Do not associate any entity with classification.

Steps:
 # Search an entity and display it in web UI. Note the _modificationTimestamp._
 # Associate the entity above with _PII_ classification.
 # Refresh the web page. Notice that the  _modificationTimestamp_ is unchanged.

*Approach Guidance*
 * _EntityGraphMapper_ should have 2 public methods that explicitly state their purpose. Say _addClassifications_ and _addClassificationWIthNoMetadataUpdate_.
 * The _addClassifications_ will update the _modificationTimestamp_, the other will not.
 * _RequestContextV1_ should be updated to have a request the ability to update or not update timestamp. This should be checked in the method: _updateModificationMetadata_.
