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 Error1: 2016-06-03 12:29:31,942
