hi Ravi,

Please check whether the file is really a "jar" type. What you can also do is you can start the program even if the jar is existing in your local FS but make sure that input and output are refering to hdfs.

hadoop jar ~/StockVolume.jar DezyreStockVolume /user/cloudera/stockvolume/input/NASDAQ_daily_prices_A.csv /user/cloudera/stockvolume/output

Thanks
