Neeru Gupta commented on ATLAS-555:
-----------------------------------
I completely agree with you [~yhemanth]. It is important to have backward
compatibility for publicly exposed APIs. but unfortunately, I could not find a
good solution either. If you notice that description is actually optional in
server side. We do have tests to create types without description. For that it
needs to go through serialization APIs. UI optional attributes issue need to be
addressed separately.
> Tag creation from UI fails due to missing description attribute

> I compiled Atlas from the master branch (git id:
> 5b748aa47b970298a3c6b0c03495b3299079cd3e) and deployed. Ran hive-import
> (which worked fine). Then tried to create a trait from the UI. This failed.
