HiveMetaStoreChecker	Verify that the information in the metastore matches what is on the filesystem.
HiveStoragePredicateHandler.DecomposedPredicate	Struct class for returning multiple values from decomposePredicate.
HiveUtils	General collection of helper functions.
InputEstimator.Estimation
Partition	A Hive Table Partition: is a fundamental storage unit within a Table.
PartitionIterable	PartitionIterable - effectively a lazy Iterable Sometimes, we have a need for iterating through a list of partitions, but the list of partitions can be too big to fetch as a single object.

Sample	A sample defines a subset of data based on sampling on a given dimension.
SessionHiveMetaStoreClient
Table	A Hive Table: is a fundamental unit of data in Hive that shares a common schema/DDL.
