@alan18080   It seems this may be related to Process Group within a Process Group ( a known bug), but its hard to know based only on this error.   You may find more verbose information in the nifi log which will help better resolve.   Here is one solution for the same:   https://community.cloudera.com/t5/Support-Questions/quot-No-Flow-Exists-quot-When-Importing-Process-Groups-with/m-p/241006   ...

@dan_lucas  Not much to go on here, but it seems like you are having some issues resolving the networking for host/hostnames and ports.  Particularly:  myip3/<unresolved>:11443   You may want to work on providing true host names and ips and trying nifi again. ... View more

@bou7miiiz are you setting the mime type in the post HEADERS from nifi to the api? The 415 error seems to be expecting "application/json".   Add this property the same way you added Authorization. ... View more

@ZorteK This is certainly an interesting scenario.   First thing i would wonder is why there is 1 out 10000 that is different.  If that is not something you can remove, then you will not able able to apply the same schema to all parts.   Its possible this is a bug with the CHOICE, but im not sure or familiar with that.   Few solutions here:  1 check for and handle the exception in a separate flow branch able to parse that second schema.   Or you can run the entire flow where the GEO value is a full string.  Do not try to parse it down to finite schema within that string.   ...

@edim2525   I have never had a concern to replicate kafka with nifi keeping exact order.    Perhaps others can respond with more details in a nifi context. That said,  my customers are using Streams Replication Manager (SRM) for heavy duty kafka replications.     https://docs.cloudera.com/cdf-datahub/7.2.16/howto-streams-replication-manager.html https://docs.cloudera.com/runtime/7.2.16/srm-overview/topics/srm-replication-overview.html There are several different form factors of SRM across private and public cloud but the doc links above should give you a good idea of what it is.   ...

@SAMSAL Thank you.     For future reference.  If you ever need to figure out what the request is,  simply use NIFI UI to do the action you want while monitoring your Developer Tools.   This will expose the full request/response on any given UI action. I have filed a JIRA for this. https://issues.apache.org/jira/browse/NIFI-12503 ... View more
