DagUtils	DagUtils.
DataInputByteBuffer
DynamicPartitionPruner	DynamicPartitionPruner takes a list of assigned partitions at runtime (split generation) and prunes them using events generated during execution of the dag.
HashTableLoader	HashTableLoader for Tez constructs the hashtable from records read from a broadcast edge.
HivePreWarmProcessor	A simple sleep processor implementation that sleeps for the configured time in milliseconds.
HiveSplitGenerator	This class is used to generate splits inside the AM on the cluster.
MapRecordProcessor	Process input from tez LogicalInput and write output - for a map plan Just pump the records through the query plan.
MapRecordSource	Process input from tez LogicalInput and write output - for a map plan Just pump the records through the query plan.
MapTezProcessor	Subclass that is used to indicate if this is a map or reduce process
MergeFileRecordProcessor	Record processor for fast merging of files.
MergeFileTezProcessor	Tez processor for fast file merging.
ObjectCache	ObjectCache.
RecordProcessor	Process input from tez LogicalInput and write output It has different subclasses for map and reduce processing
ReduceRecordProcessor	Process input from tez LogicalInput and write output - for a map plan Just pump the records through the query plan.
ReduceRecordSource	Process input from tez LogicalInput and write output - for a map plan Just pump the records through the query plan.
ReduceTezProcessor	Subclass that is used to indicate if this is a map or reduce process
SplitGrouper	SplitGrouper is used to combine splits based on head room and locality.
TezContext	TezContext contains additional context only available with Tez
TezJobExecHelper	TezJobExecHelper is a utility to safely call Tez functionality from common code paths.
TezJobMonitor	TezJobMonitor keeps track of a tez job while it's being executed.
TezProcessor	Hive processor for Tez that forms the vertices in Tez and processes the data.
TezSessionPoolManager	This class is for managing multiple tez sessions particularly when HiveServer2 is being used to submit queries.
TezSessionState	Holds session state related to Tez
TezTask	TezTask handles the execution of TezWork.
