Assumptions
 *  2004_2014.csv files is copied to HDFS and location is defined in HBASE_INPUT_PATH constant which is hdfs://156.56.179.122:9000/input

Map Reduce
==========
Steps :
    1. Insert data to HBase
        1.1 Create table(Stock2004_2014Table) and column family(Stock2004_2014CF) in HBase
            main class : StockBulkDataLoader
            mapper class : StockInsertAllMapper
            reducer class : StockInsertReducer
            data structure : row key : id_symbol, row val : col family key : date col family val : price_cap

        1.2 Create table (StockDatesTable), CF - StockDatesCF to store dates
            main class : StockDateLoader
            mapper class : StockInsertDateMapper
            reducer class : StockInsertDateReducer
            data structure : row key : date, row val : date

    2. Read Data from HBase
        Read Stock2004_2014Table content during a period and find regression (intercept, slope and error)
         main class : StockDataReader
         mapper class : StockDataReaderMapper

    3. Read data from HBase for given range and with mode and write vector files to HDFS
        command : ./bin/hadoop jar ~/chathuri/hadoop/hadoop-2.7.1/stock-kmeans-1.0.0-jar-with-dependencies.jar msc.fall2015.stock.kmeans.hbase.StockVectorCalculator 20100719 20110719 5
    5. Read vector file and calculate distance and write the distance file to HDFS
        command : ./bin/hadoop jar ~/chathuri/hadoop/hadoop-2.7.1/stock-kmeans-1.0.0-jar-with-dependencies.jar msc.fall2015.stock.kmeans.hbase.hbase.pwd.PairWiseAlignment hdfs://156.56.179.122:9000/output/20100719_20110719/part-r-00000 6031 6031
