> Currently we have provided 2 checks for the Attribute Name:
> [ATLAS-3872|https://issues.apache.org/jira/browse/ATLAS-3872] 
> Restrict typedef creation when a child type attribute conflicts with parent 
> type attribute of same name
> [ATLAS-4522|https://issues.apache.org/jira/browse/ATLAS-4522]
> Updating typedef with new supertype should be allowed only if attributes are 
> unique compared to other existing supertypes
> But in the earlier versions these checks were not there. So there may be a 
> chance of Atlas environment having such data where these checks can cause 
> problems at the time:
> 1. Atlas Startup.
> 2. Creating new typedefs
> This patch handles these scenarios and provides backward compatibility for 
> these 2 changes mentioned.
