   Not sure if this works well with Hive 2.3.x also since it is still on Guava 14.0.1.
   
   > IMO, if spark-3 with hadoop3.2 can work well in Hadoop cluster (2.6/2/7/2.8. etc), it's ok just use hadoop 3.2 client.
   
   Yes it's expected to work. There is an issue [HDFS-15191](https://issues.apache.org/jira/browse/HDFS-15191) which potentially breaks compatibility between Hadoop 3.2.1 and 2.x server but it is fixed in 3.2.2 (which Spark is probably going to use).
