Rajat Khandelwal commented on LENS-549:
---------------------------------------
LensClientSingletonWrapper is what is sounds like: a singleton wrapper for Lens
Client. The setClient method is not useful IMO. It was designed as a utility
class for users of lens-client module(e.g. lens-cli module), providing the
credential prompt code. So users of lens client don't need to write their own
code for credential prompting.
Please suggest if you have an alternative design in mind. The case you have
mentioned should be handled in LensClient#connectToLensServer. That method
should make sure all required parameters are there.
> Lens client doesn't come-up if the lens server is not available
