Yaqian Zhang commented on KYLIN-4656: ------------------------------------- Hi Gabor: I don't seem to understand what you mean. Is there an error log to let us know the details? kylin-jdbc 3.1.0.jar use a shaded guava replaced guava, and the shaded guava is 28.2-jre. > Guava classpath conflict caused by kylin-jdbc 3.1.0 jar > ------------------------------------------------------- > > Key: KYLIN-4656 > URL: https://issues.apache.org/jira/browse/KYLIN-4656 > Project: Kylin > Issue Type: Bug > Components: Driver - JDBC > Affects Versions: v3.1.0 > Reporter: Gabor Arki > Priority: Critical > > The newly released kylin-jdbc 3.1.0 jar contains a shaded, non-repackaged > version of the Guava library. This is causing class duplication with the > original guava jar if it is also on the classpath which results in > non-deterministic, runtime errors depending on which version of a certain > guava class has been picked up by the class-loader from the 2 versions. Based > on the runtime errors of the missing classes and methods, it seems to be a > very old version, probably <=14. > > Either implement a proper shading with package relocation or rely on > transitive dependency, but do not shade non-repackaged versions of libraries. -- This message was sent by Atlassian Jira (v8.3.4#803005)
