HI Jean, I'm not even near to be an expert on NIFI, but I did accomplish to put to work an scenario similar to the one you describe.
I was able to read some data, process it and store the Json payload in ES. I used HTTP invoke, instead of ES Processors. Hope it helps you.

Supports Expression Language: true (will be evaluated using variable registry only) It looks like this restriction appeared around Nifi 1.6 (as per the documentation)... is there a reason for such a limitation? My current flow was extracting the information from the input JSON document and saving the information inside a Flow attribute. What can I do about this? I don't like monkey patching.. is there any other way to get around this? Thanks
