So, looking at the source, in my case starting Java on the command-line from
the {{C:\Program Files\NiFi}} directory also does not work, because
{{/nifi-bootstrap/src/main/java/org/apache/nifi/bootstrap/RunNiFi.java}} makes
the assumption that the parent dir of the bootstrap config file will be the
root (the "workingDir") of all things NiFi. Which in my case is also not true,
as I'm putting the configuration files in a different directory: {{C:\Program
Files\My Program\nifi-conf\}}...

bootstrapConfigFile.getAbsoluteFile();}}

I just bumped into the same issue (NiFi v1.7.1). In my case, running on
Windows, I created my own batch file to start NiFi, with the lib directory of
NiFi being installed in {{c:\Program Files\NiFi}}, and all generated files
(logs, internal DB, etc.) pointed to {{C:\ProgramData\NiFi}}. (I modified
several NiFi config files to achieve this.) I happened to start the batch file
from somewhere other than the NiFi root dir in {{C:\Program Files\NiFi}}, and I
got the following exception (due to the above code):
