when create new mysql interpreter into appache zepplin, error reported as question title.

environment:

linux centos 7.3 zepplin 0.8.2, bin package installed. maven 3.1 installed.

create new mysql interpreter, according to official site step: https://zeppelin.apache.org/docs/0.8.2/interpreter/jdbc.html#mysql

enter image description here

Properties -----------------------------------------------

Name                Value
default.driver      com.mysql.jdbc.Driver
default.url         jdbc:mysql://localhost:3306/
default.user        mysql_user
default.password    mysql_password

Dependencies ---------------------------------------------

Artifact                                   Excludes
mysql:mysql-connector-java:5.1.38

when create new note and bind to mysql interpreter, it reports following:

Error setting properties for interpreter 'jdbc.mysql': Cannot fetch dependencies for mysql:mysql-connector-java:5.1.38

enter image description here

checking also the @zepplin_root_path/local-repo/mysql/mysql-connector-java/5.1.38, nothing found.

obviously the dependency is not downloaded. my question is how to download this artifact. Is the maven required for zepplin?

Thanks.

This is because downloading from Maven central repository does not work.

Default Maven Central repository of zeppelin is set to "http://repo1.maven.org/maven2/" and the above links is not working now.

According to the next article, maven repo has recently stopped supporting http requests. https://support.sonatype.com/hc/en-us/articles/360041287334-Central-501-HTTPS-Required

So, you need to add the following URL as a new repository in Zeppelin. http://insecure.repo1.maven.org/maven2/

In my case it works fine. ( zepplin 0.8.2 )

The HTTPS' URL does not work in zeppelin. Maybe for some reason Zeppelin doesn't support HTTPS.

Here is a similar article related to this topic : Apache Zeppelin not working with https for maven repo

I am having this same issue and it has just started recently. This has always worked for me in the past
