you have to go to path where nifi is installed.and that will be hdf folder which will not be found under root or your user. follow the steps to find go to cmd and hit this command ---> sudo docker exec -it sandbox-hdf /bin/bash then go to path /usr/hdf/3.1.2.0-7/nifi you will see nifi related folders. Now, create you input directory mkdir - inputdir mkdir -outputdir that's it ! use this directories in your getfile and putfile processor. Note: all folder permission should be NIFI as well as input data as well . Happy Learning! let me know if any issue posted on :Mon.Oct 22,2018 ... View more
