@toutou    From your hdfs cluster you need hdfs-site.xml and correct configuration for PutHDFS.    You may also need to satisfy creating a user with permissions on the hdfs location. Please share PutHDFS processor configuration, and error information to allow community members to respond with specific feedback required to solve your issue.   If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.

You can leverage "Attributes to send"  or if you stop processor and click + you can add custom attributes right on bottom of processor config.   If you are not getting anything out of response (failure, retry, no-retry, etc) then you definitely have a connectivity issue from Nifi outbound...  ...

@Ksad  Excellent work to completely show us what you have.  Also, excellent work to test and confirm your request work in postman first.  This is always one of the first things I do to make sure i have a valid test connection and all settings to connect to the API before attempting with InvokeHttp.    When you take this route, and you cannot get a response, this indicates a networking issue with Nifi to [salesforce domain].  You should test command line from NiFi node to [salesforce domain] using curl, wget, telnet, etc.    Next if you can confirm connectivity, attempt to adjust the processor time outs.   Some systems need longer than defaults.  For example I sometimes set to 50 and 150 by just adding a 0 to the 2 values (connection and read timeout).  f it did time out it should throw an error.  You can also set the processor log level to debug to expose more verbose output in the NiFi UI.  Last but not least,  tail the nifi-app.log file while doing all nifi flow debugging.  Sometimes more useful information is found there.   If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.

@Vamshi245  Yes,  HandleHttpRequest and HandleHttpResponse are used in tandem.  Behind the processors is a map cache which holds connection session between request/response processors.   If your flowfile (json) coming out of custom HandleHttpRequest is delivered to stock HandleHttpResponse, it will send the json to the original connecting client.   If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.

As suggested above, update post with your processor, its reader and writier settings.  It sounds like you have something misconfigured.  If possible show us a screen shot of your flow too.    ... View more

@Chigoz    Your issue with that sandbox cluster is likely too many services trying to run on too small of an instance/node.  You will need to strategically turn on the components you need individually starting with HDFS first.  If you have issues specific to the sandbox, or certain components starting, you should open a post with those specific errors.      To install HUE, check out my management pack:   https://github.com/steven-matison/dfhz_hue_mpack   Local search for "hue install" topics includes articles reference above hue mpack:   https://community.cloudera.com/t5/forums/searchpage/tab/message?advanced=false&allow_punctuation=false&q=install%20hue   If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.

You will need to define your schema in avro format, drop that into the readers/writers.   Here is an example:   { "type" : "record", "name" : "DailyCSV", "fields" : [ { "name" : "DepartmentName" , "type" : ["string", "null"] }, { "name" : "AccountName" , "type" : ["string", "null"] }, { "name" : "AccountOwnerId", "type" : ["string", "null"] }, { "name" : "AdditionalInfo", "type" : [ "null", "string" ] } ] }   ...
