Hi @tgravescs,
This is specifically for the case where new input source/output
destinations are getting added after the driver has already started. Notebooks,
long running streaming applications applications, etc - where the configuration
could be passed in dynamically.
I do agree that SparkHadoopUtil is a DeveloperApi which we are leveraging
here, is there any other api in yarn module which will be a better fit ? I did
not find, but could have overlooked.
I have other comments on the pr which I will add, but wanted to ensure
there are no high level issues with the approach. Thanks
