David Lavati commented on HIVE-22126:
-------------------------------------

I just spotted this issue: [~euigeun_chung] HIVE-21569 was recently going in a direction to shade guava as there are other issues with a simple bump, mostly wrt spark.
Maybe we can align our findings here.

> The ql/pom.xml includes complete guava library into hive-exec.jar https://github.com/apache/hive/blob/master/ql/pom.xml#L990 This causes a problems for downstream clients of hive which have hive-exec.jar in their classpath since they are pinned to the same guava version as that of hive. 
> We should shade guava classes so that other components which depend on hive-exec can independently use a different version of guava as needed.
