Re: How to verify what maxParallelism is set to?

Thanks! Do you know if it's possible somehow to verify the global
maxParallelism other than calling .getMaxParallelism? Either through
an API call or the UI?

How to verify what maxParallelism is set to?

Hi all,

How do you verify what max parallelism is set to on the job level? I do not see 
it in the 1.6 UI, for example. 

I’m setting maxParallelism to 4096 on the StreamExecutionEnvironment before 
execution but printing out the maxParallelism in an operator still displays -1. 
Since this is such an important setting I’d like some sanity check to verify it 
is the value I expect.

Any API or way I can verify?
