Hmm, from the failed tests below:
org.apache.spark.sql.hive.DataSourceWithHiveMetastoreCatalogSuite
org.apache.spark.sql.hive.HiveExternalCatalogSuite
org.apache.spark.sql.hive.StatisticsSuite
Since Guava 20, `com.google.common.collect.Iterators.emptyIterator()` is not
public anymore. But I don't get it because Hive 2.3.8/2.3.9 shaded guava in
hive-exec. Why it will use the newer guava upgraded here?
```
java.lang.IllegalAccessError: tried to access method
com.google.common.collect.Iterators.emptyIterator()Lcom/google/common/collect/UnmodifiableIterator;

```
I seems figured it out. Verifying it locally...
