public HiveAccumuloRowIdColumnMapping getRowIdMapping() {
    return rowIdMapping;
  }
Create a mapping from Hive columns (rowID and column) to Accumulo columns (column family and
qualifier). The ordering of the {@link ColumnMapping}s is important as it aligns with the
ordering of the columns for the Hive table schema.

@param serializedColumnMappings
         Comma-separated list of designators that map to Accumulo columns whose offsets
         correspond to the Hive table schema
