Zoltan Haindrich commented on HIVE-22126: ----------------------------------------- [~zhengchenyu]: yes that's an option - however I've not seen this in hive-3 before - but for hive-4 the same was done (HIVE-23593) you may already know it - the issue behind this is that a shaded calcite may pull in thru reflection classes from the "non-shaded" version and that will wreck some havoc there was an attempt to make a better fix than that; but it's not yet read (HIVE-23772) > hive-exec packaging should shade guava > -------------------------------------- > > Key: HIVE-22126 > URL: https://issues.apache.org/jira/browse/HIVE-22126 > Project: Hive > Issue Type: Bug > Reporter: Vihang Karajgaonkar > Assignee: Eugene Chung > Priority: Major > Fix For: 4.0.0 > > Attachments: HIVE-22126.01.patch, HIVE-22126.02.patch, > HIVE-22126.03.patch, HIVE-22126.04.patch, HIVE-22126.05.patch, > HIVE-22126.06.patch, HIVE-22126.07.patch, HIVE-22126.08.patch, > HIVE-22126.09.patch, HIVE-22126.09.patch, HIVE-22126.09.patch, > HIVE-22126.09.patch, HIVE-22126.09.patch > > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
