logback.xml location inside of the application jar file

[Pope Xie]

Hi,

   According to http://docs.cask.co/cdap/3.5.1/en/developers-manual/advanced/application-logback.html?highlight=logback, a logback.xml can be packaged into the jar file. The question is the logback.xml location inside of the application jar file. Should it be / or /resources.

Thanks

Pope Xie

Hi,

It should be just “/logback.xml”. If you use maven for your project, by default everything under “src/main/resources” will be copied inside the project jar at “/“.

Terence,

   Thanks for your answer. I put it under /. The log file is created. But nothing wrote to the log file. 

Thanks

Hi,

Would you mind share how’s the content of the logbook.xml looks like?

Hi,

Does the directory "/home/cdap/logs/“ exists and writable by the container user on all nodes in the YARN cluster?

[Pope Xie]

Yes. The directory exists. And a debug.log was created in it. But the log file is 0 empty.

Hi,

Are you able to access the container logs (stdout, stderr, program.log)? It might shows error if it is related to the logback configuration.

Hello Pope, 

I just wanted to follow up with you to see if you got a chance to look into the container logs being accessible or not ? 

Looking forward to your reply. 

Thanks,

Rohit

[Pope Xie]

There is no container log file. The logger is in a CDAP service.

Thanks

Hi Pope,

Just to confirm, without the logback.xml inside the application jar, you see log files correctly under the container log directory (you'll found at least 4 files, stdout, stderr, program.log and gc.log.*), is that right. After you added the logback.xml file as you shown above to the "/logback.xml" location inside the application JAR, you don't get any log files under the path that you setup in the logback.xml, right? How about the container log directory, is there any file there?
