   @ouyangxiaochen @dongjoon-hyun I ran into this today and this is what the issue is: Hadoop 3.2.1 updates from Guava 11 to Guava 27:
   https://github.com/apache/hadoop/blob/branch-3.2.1/hadoop-project/pom.xml#L95
   
   I think we may need to match this, not least of which because Guava is such a problem dependency that updates have to happen in a major release, probably. (Kind of surprised to see that in a maintenance release of Hadoop). Previously we'd been reluctant to vary from Hadoop, but, for Hadoop 3 profiles, seems like we need to try?
   
   Do you want to try that in this PR as part of moving it along?
