Sir We have also tried the option of putting JCUBLAA in hadoop jar. Still it does not recognise. We would be thankful if you could provide us with a sample exercise on the same with steps for execution I am herewith attaching the error file Thanking you with warm regards Dr G sudha Sadasivam

First of all, you need to specify clearly about your Hadoop environment, (pseudo distributed or real cluster) Secondly, you need to clearly understand how hadoop load job's jar file to all worker nodes, it only copy the jar file to worker nodes. It does not contain the jcuda.jar file. MapReduce program may not know where it is even you specify the jcuda.jar file in our worker node classpath. I prefer you can include the Jcuda.jar into your wordcount.jar. Then when Hadoop copy the wordcount.jar file to all worker nodes' temporary working directory, you do not need to worry about this issue. Let me know if you meet further question.
