Run a c++ program using opencv libraries in hadoop
Hi
How can I run c++ programs using opencv libraries in hadoop?
So far I have done MapReduce jobs in Java only..and there we can supply
external jars using command line itself.
And even tried using python language also..to run them we use hadoop
streaming API.
But I am confused how to run C++ programs using opencv libraries.
Thanks in Advance.

You could run it as a shell action using Oozie. Write a shell script to run
your application. Put all the application's dependencies (e.g., *.so) into
a lib directory. Put the shell script in the parent directory of that lib
directory that I just mentioned. Create a simple Oozie workflow that runs
that shell script. Save the workflow.xml that you just created to put the
shell script in. Finally, make a directory on HDFS and put all of it in
that directory. Oozie will run that shell script in a single-map,
no-reducer job.
