PutAzureEventHub issue - incoming flow files will get stuck if configured Event Hub Namespace is invalid

[#1]

Hi 

When 'Event Hub Namespace' is set with invalid, incoming flow files are getting stuck (not moving to failure relation) and also its keep on opening connection (files) and which is making Nifi is to go down..

Any suggestion how can I take care of this ?

In my use case these 'Event Hub Namespace' and other fields are configured from an UI by an end customer so possibility of invalid data

Thanks
