Subject: Re: Custom processor is failing for the custom processor

Hello,

Would you be able to share your code for PutFileAzureDLStore so we can help identify if there
is a concurrency problem?

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
