Java error when running Mapreduce program

Question

I have a MapReduce Program which aggregates the total stock volume in a stock exchange data set. I have compiled & created a jar file without any errors. But when i run the jar on Hadoop cluster it throws me a java class notfound exception. I am new to java and any help will be greatly appreciated

cloudera@cloudera-vm:~$ hadoop jar NYSE.jar -D com.rashmi.mapreduce.NYSE.NYSEJob /user/NYSE/NASDAQ_daily_prices_A_sample.csv /user/NYSE/outputException in thread "main" java.lang.ClassNotFoundException: -D

Answer 1

Hi please correct the command as:

hadoop jar NYSE.jar com.rashmi.mapreduce.NYSE.NYSEJob /user/NYSE/NASDAQ_daily_prices_A_sample.csv /user/NYSE/output

You need not use -D option here.
