@Bhushan Babar And you have created a new user in your authorizer that matches the following exactly: cn=nifiuser+o=tp1+ou=business,dc=example,dc=com Thanks, Matt

@Fawn Nguyen How are are the Files being moved to this directory. To understand what is happening here, let me explain how the listFile decides what files to list in a source directory. The List type processors all keep "state". It would be very expensive to record information about every File listed and then compare any new listing against that list each time a list based processor runs. So what is recorded in state management is the latest time stamp of the lats batch of files listed. So on next run the list based processors will only list files with newer timestamps and then update state again. It is my guess that the method which you are suing to "move" these new sets of files in to this directory is not resulting in a update of the file timestamp. So only the few files that actually have newer timestamps then what was last recorded in state are being listed. You will need to change how you are moving files in to this directory to make sure all the file's timestamps are updated. A move operation typically does not update the timestamp, but a copy will. Thanks, Matt

@Alejandro A. You can use the replaceText processor to do this. It offers prepend and append replacement strategies. Just provide the name of the FlowFile Attribute you which to append or prepend in the "Replacement Value:" property of the processor in the form of a NiFi Expression Language statement. ${<flowfile-attribute-name>} Thanks, Matt

@Muhammad Umar This Error is being thrown by your MoveFile.bash script and not by NiFi. NiFi is simply capturing the error response from the script and putting in tin the NiFi app log. Thanks, Matt

@Tinkle Mahendru By default the MergeContent processor is configured with "Minimum Number of Entries" set to 1. When the processor run it looks at the current incoming queue and bins FlowFiles based on its configuration. if the incoming queue only has 1 FlowFile in it at the time it runs it will merge because it met the min value above (basically file passed through with no merging). So you will need to play around wit the configs for this processor to get your desired results based on your dataflow needs/volume. Matt

@regie canada The extractText processor creates FlowFile attributes from the extracted text. NiFi has an AttributesToJSON processor you can use to generate JSON form these created attributes. For new questions, please open a new question. It makes it easier for community users to search for answers. Thanks, Matt

@Bhushan Babar When NiFi compares a users authenticated DN against the file based authorizer, the entries must match exactly (case sensitive and spaces count) . Can you share your nifi-user.log entries you see when you try to log in with the new user? Matt

@regie canada I agree. My answer was only intended to show how to split you multi-record file in to single records to be processed similar to @Eyad Garelnabi suggested approach. Matt

@Alvin Jin NiFi uses locally mounted storage for all four of its repositories. There is no support for external repositories unless you can mount them as a local addressable disk. Thanks, Matt
