Zeppelin: misconfiguration - apache-zeppelin

Question

I'm getting this error message when I'm trying to run my zeppelin:
OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0
WARN [2020-05-25 09:08:31,181] ({main} ZeppelinConfiguration.java[create]:159) - Failed to load configuration, proceeding with a default

I'm deploying zeppelin without any configuration.
EDIT:
Additional error message after having set ZEPPELIN_PORT:

Answer 1

It looks like you're using links with Docker compose, or something like, so it defines the ZEPPELIN_PORT environment variable for Zeppelin container that has a form of tcp://172.30.239.172:80. But this environment variable should contain only port, like, 80, or 8080.
To fix the problem try to rename linked container from zeppelin to something else, so it won't override the environment variable that is used by Zeppelin itself.
