> Currently, connector code can be seen as part of user code. Usually, users 
> only need to add the corresponding connector as a dependency and package it 
> in the user jar. This is convenient enough.
> However, connectors usually need to interact with external systems and often 
> introduce heavy dependencies, there is a high possibility of a class conflict 
> of different connectors or the user code of the same job. For example, every 
> one or two weeks, we will receive issue reports relevant with connector class 
> conflict from our users. The problem can get worse when users want to analyze 
> data from different sources and write output to different sinks.
> Using separate classloader to load the different connector code could resolve 
> the problem.
