Subject Re: Fetch Contents of HDFS Directory as a Part of a Larger Flow
Date Thu, 03 May 2018 19:57:37 GMT
Shawn, I am not answering your question but I am curious how you would see
logistics of  HTTP Request and Response Processors. Is your intent to build
REST api entirely in NiFi? I asked a question here before as I had a
similar idea but was told it was not a good strategy as it would be
difficult to sync request/response.
