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. | | Chen | | On Tue, Sep 25, 2012 at 12:38 AM, sudha sadhasivam < | [email protected]> wrote: | | > Sir | > We tried to integrate hadoop and JCUDA. | > We tried a code from | > | > | > http://code.google.com/p/mrcl/source/browse/trunk/hama-mrcl/src/mrcl/mrcl/?r=76 | > | > We re able to compile.
