@quangbilly79 NO, you should not be adding gateway to every node.   This gateway should only be installed on the edge/utility nodes, where you give access to external systems and users.   These gateway nodes then are able to reach rest of the service(s) nodes. ... View more

@rafy   I got the same issues when I tried to create a flow using RPATH.   However, here is a solution i found to dial into the data array and match on the room = A:   SELECT * FROM FLOWFILE WHERE room = 'A' I used QueryRecord With JSONTreeReader (see below) and JSONRecordSetWriter (default).

@ryu Excellent questions here.  I will address each below:   So when I am asked like in an interview or something, they ask what CDH version do you use, and when i say CDH 7.2.16, the people interviewing me asks "are you sure?" Yes, you are sure.  Even new versions of CDP, have CDH in the artifact filenames: 7.1.4-1.cdh7.1.4.p37.14288300   So is there a CDP version of CDH vs maybe on prem version of CDH Current versions of our platform are CDP 7.x.  Previous versions are CDH 6.x and older. There is On Prem CDP called CDP Private Cloud Base.  There is Public Cloud CDP called CDP Public Cloud in Aws, Azure, and GCP.   Is there some difference in versioning between on prem or CDP etc? This is my favorite question.   The differences between CDP on Prem and CDP in the cloud are going away quickly.   It is part of our modern data architecture for workload movement from on prem to the cloud to have the least amount of differences as possible.     As such, these 2 different form factors of CDP are getting closer and closer to parity.    ...
