Running hive 3.1.1 against Hadoop 3.2.0 crashes when running 'select * from employee' with
java.lang.IncompatibleClassChangeError: Class com.google.common.collect.ImmutableSortedMap does not implement the requested interface java.util.NavigableMap
Commands like show tables all run fine and data is loaded ok from the CLI as well.
Checked various other commands and e.g. data is loaded etc. Uses MySQL as metastore with MySQL-connector-java-5.1.47.jar. The only other observation is that sometimes I get
WARN DataNucleus.MetaData: Metadata has jdbc-type of null yet this is not valid. Ignored
which other people seem to get as well and seems not to impact me here. Anybody seen this as well? Help greatly appreciated ...

Perhaps it's a late answer, but I did run into the same issue. In my case, I found that the hive-exec Maven artifact's jar file is shading the Google collections framework. Now, since I've seen that other Hadoop/Hive artifacts also make use of Google Guava (version 11 if I'm not mistaken), there's a good chance that calcite will find the wrong class definition for ImmutableSortedMap (from Guava 11).
For me, excluding guava from the Hadoop/Hive artifacts that my code uses made calcite find the correct class version from Google collections.

This is probably an issue that should be reported to the Hive project, since these kinds of class path collision errors are hard to diagnose. Internally shaded artifacts should have the project's own package prefix to indicate explicit shading of the external code in question.
Oh well. Hope this helps.
