> Oh I didn't even realize that Spark is using `hive-exec-core` jar. Does that mean it doesn't take advantage of the Guava shading from Hive 2.3.8+ at all? Yea, I'm afraid that it is true. If we want to completely isolate dependencies from Hive, we may need to relocate all included (but not relocated) dependencies in `hive-exec` w/o classifier. > One idea is to have Spark use [`hadoop-shaded-guava`](https://github.com/apache/hadoop-thirdparty) which is also 30.1.1-jre. It also makes sure that Spark always use the same Guava version as Hadoop. Even Spark uses `hadoop-shaded-guava`, but `hive-exec` still needs older Guava if we cannot use the version w/o classifier (due to other dependencies e.g. common-lang3, orc, parquet..) -- This is an automated message from the Apache Git Service.
