Okay ! after a bit of search on stackoverflow I came across the command `sudo chown -R $USER:$USER /home/rahul/nifi-1.6.0` that will give the permission to the folder to alter the changes with permission to read and write, and Bingo !!! it worked . And after firing the command mentioned in above, there is no error as following : Exception in thread "main" java.io.IOException: /home/nifi-1.6.0/run directory does not have read/write privilege Thanks @Matt Clarke @Jay Kumar SenSharma ...

@Rahul Kumar - Where are you getting the nar or jar for this custom influxdb processor from? - Once you have this custom processor nar/jar file, you will want to create a custom lib directory to place it in and then configure your nifi to read that additional custom lib folder location. This is done by adding a new key/value pair to the nifi,properties configuration file: nifi.nar.library.directory.custom-lib=/<path to custom lib dir>/custom-lib - A restart of NiFi will be required before NiFi will load any newly added custom libraries. At that point the new processor shoudl be available to add to the canvas just as you add any other processor. - Thank you, Matt ... View more
