@MattWho    Hi Matt,  Thanks for the reply.  I am sending a 1kb file over the rest endpoint of a different IP machine. What I am asking here is how do I configure the invokeHTTP request using IP address?    Example: Machine 1 ( 192.168.4.1)  which contain NiFi (GetFile processor --> invokeHTTP processor) to Machine 2 (192.168.3.1) which contain the Wildfly restful webservice.    Thanks.   ...

Current setup, there are 2 computer machine 1) First machine (IP of 192.168.4.1) It contain the NiFi setup as show in the image below: Inside the NiFi setup, I get a file from a local directory and I invoke a HTTP POST to send over to the second machine which hit the Wildfly Restful Webservice endpoint. Below image show the configuration I have done inside the Invoke HTTP:   (Note: the Remote URL:  http://192.168.3.1:8081/JaxRS-Nifi/restapi/multipart/upload  )   2) Second machine (IP of 192.168.3.1)   It contain a Wildfly Restful Webservice which allow my first machine to hit the webservice endpoint. Error that I am facing:     I have a problem which the first machines doesn't send a HTTP POST over to the Second machines. I am currently looking for solutions on what are the different configurations should I do to make a NiFi HTTP over to hit the Restful Webservice endpoint?   Thanks. Appreciate if there is anyone who can help me.       ... View more

Hi,    I got a problem while sending a Zero Byte flow file through Nifi PutSFTP processor. Wondering if there is some configuration I have to set? thanks.   Use case:  get a file from a directory (GetFile Processor)  send the file through SFTP (PutSFTP Processor) if success, change the filename to new filename (UpdateAttribute Processor) Remove the all of the content (ReplaceText Processor). Zero Byte flow file  send the new filename through SFTP (PutSFTP Processor)   I gotten this error while sending Zero Byte flow file over using PutSFTP Processor PutSFTP[id=1a091db4-1f9e-14cd-5206-1514485febc8] Rejecting StandardFlowFileRecord[uuid=247457a8-6608-4271-a626-3c016a1bbe7c,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1618805512561-40, container=default, section=40], offset=15043, length=0],offset=0,name=AS_MPS_20200927_010010.xml.done,size=0] because it is zero bytes   It will be great if someone could help me.    Thanks in advance.  ...

Hi, Thanks for the good explanation.  What would be the jolt specification for the following input/output.    There are two input Json:    1st Json input:  {   "Name" : "Alvin",   "Status" : "Single",   "Life" : [ {     "Sport" : "Swimming",     "Singing" : "K-box",     "Food" : "Burger",     "Alcohol" : "Rum"   }, {     "Sport" : "Boxing",     "Singing" : "party world",     "Food" : "Chicken Wing",     "Alcohol" : "Whisky"   }, {     "Sport" : "Running",     "Singing" : "KTV",     "Food" : "Muffin",     "Alcohol" : "Martel"   }] }   2nd Json input:  {  "Name" : "Alvin",  "Status" : "Single",  "Life" : {    "Sport" : "Swimming",    "Singing" : "K-box",    "Food" : "Burger",    "Alcohol" : "Rum"  } }   This two Json message input should go to a   same JoltTransformJson processor   and come out with the following output:   1st Json output:  { "Name" : "Alvin", "Status" : "Single", "Sport" : [ "Swimming", "Boxing", "Running"], "Singing" : [ "K-box", "party world" , "KTV"], "Food" : [ "Burger", "Chicken Wing" , "Muffin"], "Alcohol" : [ "Rum", "Whisky", "Martel"] }   2nd Json output:  { "Name" : "Alvin", "Status" : "Single", "Sport" : [ "Swimming"], "Singing" : [ "K-box"], "Food" : [ "Burger"], "Alcohol" : [ "Rum"] }   How can I configure the JoltTransformJson processor to get the above output? Or is there any other ways to do it? Please advise with step and example. appreciate ... View more
