Bharat Viswanadham commented on HDDS-155:

 Hi [~hanishakoneru]  

Thanks for review.

Addressed review comments in patch v03.

{quote}{{testUpdateContainerInvalidMetadata}} - Should we not be allowed to 
update the value for an existing key in containerData#metadata?{quote}When we 
have the same key in the metadata, and when try to add the same key again, we 
are returning error from ContainerData. Actually, in the current code, 
updateContainer and metadata are not used. I think we can change this 
implementation when metadata comes into the picture and according to its use 
case. Let me know if this is okay with you?
