Zoltan Matyus created HIVE-21584: ------------------------------------ Summary: Java 11 preparation: system class loader is not URLClassLoader Key: HIVE-21584 URL: https://issues.apache.org/jira/browse/HIVE-21584 Project: Hive Issue Type: Task Components: Hive Affects Versions: 4.0.0 Reporter: Zoltan Matyus Assignee: Zoltan Matyus
Currently, Hive assumes that the system class loader is instance of {{URLClassLoader}}. In Java 11 this is not the case. There are a few (unresolved) JIRAs about specific occurrences of {{URLClassLoader}} (e.g. [HIVE-21237|https://issues.apache.org/jira/browse/HIVE-21237], [HIVE-17909|https://issues.apache.org/jira/browse/HIVE-17909]), but no _"remove all occurrences"_. Also I couldn't find umbrella "Java 11 upgrade" JIRA. This ticket is to remove all unconditional casts of any random class loader to {{URLClassLoader}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
