I have installed HDF using the below command in my hortonworks sandbox:
./install-nifi.sh ~/root/HDF-1.2.0.1-1.tar.gz sandbox.hortonworks.com 2222 1.2.0.1-1
Post Installation, I have started the nifi, Nifi is up and running but I am not able to access the nifi web interface.
Note:I have verified the port number 6434 in the nifi.properties file, that looks good.
Kindly let me know if you have solution for the above
