I have been trying to launch NiFi, but everytime I do so I get the following error:

I understand this is coming from "calculateMd5sum " function that calculates md5 sum of a specified file. However, I have made no changes to any of Nars neither have I added any custom nars. The same instance did launch before.
I have also tried to start afresh by extracting the setup again, however I face the same error. I fail to understand why the issue is coming up all of a sudden. Please help!
I got it.
My java home pointed to "C:\Program Files\Java\jdk1.8.0_65"
changed the path to "C:\Program Files (x86)\Java\jre1.8.0_121"
It works fine now.
Thanks #BryanBende

I have a setup in which NiFi Web Server suddenly started failing to start when upgrading from 1.15.3 to 1.16.1 version. The following exception keeps occurring on the Apache NiFi Cluster:

I have already tried to tear it all down and re-install 1.15.3 with not any other changes, but the same issue still persists. Can someone please share any ideas if there are any on how to fix this?
When I run run-nifi.bat it pops up for a split second but then auto closes. I don't really understand this, I just need it for a university class and it hadn't been properly explained, so I'm just trying on my own really.
I get this in my nifi-app.log:

I've tried editing the web properties in the config files in case the default was wrong. Right now it's on, but the errors are the same:
nifi.web.http.host=localhost
nifi.web.http.port=9090
nifi.web.http.network.interface.default=
I have Windows 10 Home Edition.
NiFi requires Java 8 or Java 11 to run. So your environment variables should point to the correct directory with Java 8 or Java 11.
Have you tried setting the JAVA_HOME environment variable? I would recommend checking the config files and telling the configs where to find the Java installation
You might be missing URL ACL
Maybe you can try below command:
netsh http add urlacl url=http://computername:port/ user=username

I ran into this issue when the folders pointed to by nifi.nar.library.directory.* was inaccessible, e.g. the Symbolic links were no longer valid due to file system changes.
Fixed the links and the server came up.
sudo chown -R nifi:nifi /opt/nifi/
sudo service nifi start
worked for me.
I'm only attempting to launch the Nifi UI as a local instance to start playing with it. I've unzipped the package and made sure to set the JAVA_HOME variable to my Java 1.8. When I try to bin/run-nifi, in my nifi-app log, the error message is:

I've followed the installation instructions and haven't been able to trouble shoot. How do I load these NAR files upon running Nifi?
Thanks
I believe the underlying error in your output is java.io.IOException: Z:\DoE\LOCAL-~1\NIFI-1~1.0\.\work\nar\framework could not be created.
NiFi requires file permissions to create and write several directories, there is a list in the NiFi Admin Guide: How to install and start NiFi. NiFi does this to unpack the NAR files, write logs, and for various data repositories that comprise your data flow.
You have a few options:
Modify the permissions of the directory to allow NiFi read/write access. This can be done for each individual child directory.
Copy the entire NiFi distribution to a read/write location and run it from there.
Edit the conf/nifi-properties file to change the locations of these directories to read/write locations. See NiFi Admin Guide: System Properties for help on the properties.
Symlinks are a great solution for systems that support symlinks.
Two things you can try:
Run NiFi with administrator privilege (not a good practice) by going to ~\<NIFI_INSTALLATION_DIR>\bin and right click run-nifi.bat. Click Run as Administrator
Move NiFi directory to a location where the logged in user has full access to. Ex: C:\Users\<YOUR_USER>\Documents\. Now try to execute bin\run-nifi.bat
Similarly to the resolution that James proposed. I had to do the below 3-step process.
My scenario: I'm using docker containers and had the same problem. Even changing the user of my container to root didn't work. So, I did the following:
1 - Download Minifi https://nifi.apache.org/minifi/download.html
2 - Untar and execute the Minifi agent on my own laptop (I'm using MAC) so that the necessary folders and files will be created.
3 - Tar it up again and add to the DockerFile of my container creation
Done! Everything worked fine after that.
I configured a local Nutch 2.3.1 instance on MacOS 10.11.5 (El Capitan) running in Eclipse as described here: https://wiki.apache.org/nutch/RunNutchInEclipse
As data store to use I configured MongoDB 2.6.12 which is also running on my local MacOS machine. I took the Gora config from here: http://www.aossama.com/search-engine-with-apache-nutch-mongodb-and-elasticsearch/
ivy.xml

# I tried several server settings like localhost, 127.0.0.1, 127.0.0.1:27017, ...
gora.mongodb.db=nutch
I did not change gora-mongodb-mapping.xml.

After two days I've run out of ideas.
Within the log file I can't identify any valuable hint. The MongoDB logs don't show any connection attempts (not to mention an active connection). Using mongo I'm able to connect to the database and requesting http://localhost:27017 shows the expected message ("It looks like you are trying to access MongoDB over HTTP on the native driver port.") and corresponding log file entries. If I switch the data store to Cassandra, injecting works as expected, so Nutch itself also seems to work.
Does anybody know what I'm missing or understand what the hadoop.log is trying to tell me?
Any help would be appreciated! Thx.
Update: I also tried to use this configuration on an Ubuntu 14.04 server - works as expected. So I suppose my issue is related to the connection between Nutch & MongoDB running on a Mac. (If somebody wants to know: I'm trying to get the configuration working on my Mac because I want to do some local development with no need of a server connection.)
