Hello,
I wrote the following custom service control and processor. When the custom
processor is running concurrently, it's failing often with several different
errors. Are there any special handlings for concurrently that I need to add in
the custom processor? I wrote the sample Java program which does the same
thing as the custom processor (authenticate every time the file is
created/create a file, create 2 threads and run concurrently), it's working
fine. The custom processor also fine when this is not running concurrently.
Custom service control - set the properties for the Microsoft Azure Datalake
Store
Custom processor - authenticate, then create a file in Microsoft Azure Datalake
Store
