Stamatis Zampetakis commented on HIVE-26226: -------------------------------------------- Since jdk.tools comes from a dependency with provided scope then if compilation and tests run fine after removal I guess it is safe. There are some caveats though cause if the existing tests do not reach the code which needs the removed dependency then by removing a dependency we could be breaking something without noticing. However, I doubt that jdk.tools are ever needed at runtime so we should be good to go. Other than that I am a bit skeptical about the upgrade-acid module and compilation with JDK 11. The {{PreUpgradeTool}} is meant to run with Hive 2 binaries which are compiled with jdk <= 8. What will happen if we now compile the {{PreUpgradeTool}} with JDK11? Which JDK should the end-user use to run the {{PreUpgradeTool}}? > Remove outdated dependency to jdk.tools:jdk.tools:jar:1.7 (upgrade-acid) > ------------------------------------------------------------------------ > > Key: HIVE-26226 > URL: https://issues.apache.org/jira/browse/HIVE-26226 > Project: Hive > Issue Type: Improvement > Components: Tests > Affects Versions: 3.1.3, 4.0.0-alpha-2 > Reporter: Sylwester Lachiewicz > Priority: Minor > > The hive-metastore 2.3.3 used in upgrade-acid tests includes unnecessary > dependency - that blocks the possibility to compile with newer java versions > > 8 -- This message was sent by Atlassian Jira (v8.20.7#820007)
