    Utility for TableMap and TableReduce
    org.apache.hadoop.hbase.mapred.TableOutputFormat
    Convert Map/Reduce output and write it to an HBase table
    org.apache.hadoop.hbase.mapred.TableOutputFormat.TableRecordWriter
    Convert Reduce output (key, value) to (HStoreKey, KeyedDataArrayWritable) and write to an HBase table.
    org.apache.hadoop.hbase.mapred.TableRecordReader
    Iterate over an HBase table data, return (Text, RowResult) pairs
    org.apache.hadoop.hbase.mapred.TableRecordReaderImpl
    Iterate over an HBase table data, return (Text, RowResult) pairs
    org.apache.hadoop.hbase.mapred.TableReduce<K extends org.apache.hadoop.io.WritableComparable,V>
    Write a table, sorting by the input key
    org.apache.hadoop.hbase.mapred.TableSnapshotInputFormat
    TableSnapshotInputFormat allows a MapReduce job to run over a table snapshot.
    org.apache.hadoop.hbase.mapred.TableSnapshotInputFormat.TableSnapshotRegionSplit
     
    org.apache.hadoop.hbase.mapred.TableSplit
    A table split corresponds to a key range [low, high)
