FieldDesc
LlapArrowBatchRecordReader
LlapArrowRecordWriter<K extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.Writable>	Writes Arrow batches to an ArrowStreamWriter.
LlapArrowRowInputFormat
LlapArrowRowRecordReader	Buffers a batch for reading one row at a time.
LlapBaseInputFormat<V extends org.apache.hadoop.io.WritableComparable<?>>	Base LLAP input format to handle requesting of splits and communication with LLAP daemon.
LlapBaseRecordReader<V extends org.apache.hadoop.io.WritableComparable>	Base LLAP RecordReader to handle receiving of the data from the LLAP daemon.
LlapBaseRecordReader.ReaderEvent	Define success/error events which are passed to the reader from a different thread.
LlapCacheAwareFs	This is currently only used by Parquet; however, a generally applicable approach is used - you pass in a set of offset pairs for a file, and the file is cached with these boundaries.
LlapDump	Utility to test query and data retrieval via the LLAP input format.
LlapInputSplit
LlapNodeId
LlapOutputFormat<K extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.Writable>
LlapOutputFormatService	Responsible for sending back result set data to the connections made by external clients via the LLAP input format.
LlapRecordWriter<K extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.WritableComparable>
LlapRowInputFormat
LlapRowRecordReader	Row-based record reader for LLAP.
LlapStorageHandler
LlapUtil
LlapUtil.StatisticsData
NotTezEventHelper	See NotTezEvent class/.proto comment.
