Jonathan Turner Eagles commented on TEZ-4100: --------------------------------------------- It's a little more complicated the way I see this. To increase compatibility, can neither upgrade nor stay the same. If Tez upgrades, then users using older versions of guava will no longer work. If Tez stays the same, hadoop 3+ continues to break. If we upgrade with need a second step to help compatibility, we can either remove the Precondition.check apis with some equivalent or we can shade guava to ensure separation between what Tez depends and what Tez users depend. > Upgrade to hadoop 3.1.3 > ----------------------- > > Key: TEZ-4100 > URL: https://issues.apache.org/jira/browse/TEZ-4100 > Project: Apache Tez > Issue Type: Improvement > Reporter: László Bodor > Assignee: László Bodor > Priority: Major > Attachments: TEZ-4100.01.patch > > -- This message was sent by Atlassian Jira (v8.3.4#803005)
