> After the Guava 20 upgrade, there was a major bug in the Hive registration
> code where fields could be casted as an unexpected type in
> HiveRegistrationUnit
> {code:java}
> protected static <T> Optional<T> populateField(State state, String key,
> TypeToken<T> token) {
> {code}
> The field setter is returning an Optional generic, which allows the code to
> compile but fail during runtime as the types are mismatched, leading to a
> casting exception when reading the type e.g.
> {code:java}
> java.lang.ClassCastException: java.lang.String cannot be cast to
> java.lang.Long at
> org.apache.gobblin.hive.metastore.HiveMetaStoreUtils.getTable(HiveMetaStoreUtils.java:111)
> {code}
