I have installed XAMPP on my windows 7 machine but can't get Apache to work.
After opening the XAMPP panel and installing Apache service: I have tried start it, it always get stuck at "Starting apache service..."
On start I get the following:
7:36:57 [main] Initializing Modules
7:36:57 [main] The MySQL module is disabled
7:36:57 [main] The FileZilla module is disabled
7:36:57 [main] The Mercury module is disabled
7:36:57 [main] Starting Check-Timer
7:36:57 [main] Control Panel Ready
7:37:02 [main] Executing "services.msc"
7:41:50 [Apache] Attempting to start Apache service...
Event Viewer:
The Apache service named
reported the following error: >>>
httpd.exe: Syntax error on line 172 of C:/xampp/apache/conf/httpd.conf: Cannot load modules/mod_ssl.so into server: The specified module could not be found.
I also get an ERROR for the .NET Runtime Optimization Service:
.NET Runtime Optimization Service (clr_optimization_v2.0.50727_32) - Failed to compile: PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 . Error code = 0x80070002
PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
On the first start i had some .dll problems but i solved them, I do not know if it is related.
I already tried everything in:
"XAMPP - Apache could not start - Attempting to start Apache service"
without improvement.
Any advice on how I could resolve this ?
Thanks
Go to Xampp control panel and click on config->httpd.conf then go to line no 171 and change
ServerName localhost:80
with
ServerName localhost:81
It will work.

Tomcat is not up for Oracle Apex because it's pointing to a wrong path which does not exist. Is there a way to fix this? below is the error message.
INFO [main] . No pools configured yet
SEVERE [main] oracle.dbtools.common.logging.LegacyLoggingAdaptor.severe Error writing to:

If I just run the StartSonar.bat everything works and starts fine.
If I setup a service to run using NSSM using:
Path: ..\blah\wrapper.exe
Startup directory: ..\blah
Arguments: -c ..\blah\conf\wrapper.conf
I get an error in the logs that says:

That leads me to believe there is a problem with setting up the database correctly, but once again.. if I run the StartSonar.bat everything works fine.
The only thing I can think of is that I am setting up the service as a "Local System account," instead of when I run the bat it would be from my own account.
That being said, I cannot use my account and then login and change my password or something every time my AD changes.
I have recently installed NiFi, and it was working fine for few days. But suddenly today when i try to open it using run-nifi.bat, the NiFi window is getting closed in few seconds stating the below error:
2019-04-11 23:07:40,146 WARN [NiFi Bootstrap Command Listener] org.apache.nifi.bootstrap.RunNiFi Failed to set permissions so that only the owner can read status file C:\Users\DOWNLO~1\NIFI-1~1.1-B\NIFI-1~1.1\bin\..\run\nifi.status; this may allows others to have access to the key needed to communicate with NiFi.

I do looked out for the org.apache.nifi.StdErr Failed to start web server: Must configure HTTP or HTTPS connector error, but unfortunately I cant find a similar one. I'm sure that no settings or properties has been changed since installation. Any suggestion guys?
I was getting the same error.
You need to check nifi-app.log file to get more details on this type of error.
Here’s what I did: Remove the port information from nifi.properties for HTTPS and only keep the setting for HTTP. Then restart nifi again.
Keep one property enable like https or http. in my case https:127.0.0.1:8443/nifi/
it works fine 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 am trying to connect to a sqoop server on localhost:
sqoop:000> set server --host manager --port 12000 --webapp sqoop
Server is set successfully
sqoop:000> show version -all

Why is this happening?
Hadoop libraries need to be set in a file named catalina.properties inside directory server/conf. In this file, you need to set the hadoop libraries path in common-loader property. Default will be /usr/lib/hadoop and /usr/lib/hadoop/lib. If you have your hadoop libraries at any different locations then point that directory in this property.
sqoop2-tool verify can be used to verify all the sqoop server configurations. If it is successful, you can start your server using sqoop2-server start.
