Github user ajantha-bhat commented on the issue: https://github.com/apache/carbondata/pull/2733 @chenliang613 : All presto test case failed because of de-serialization error from antlr jar. In the pom.xml of presto db master code. https://github.com/prestodb/presto/blob/master/pom.xml antlr 4.7.1 is used. our pom has a different version. Hence this error. please change out presto pom.xml antlr version to **4.7.1** and re run the CI I have tested locally with this change. All test case passed
