Amazon EMR has changed it's hadoop version from 2.7.3 to 2.8.3 and there is no option for 2.7.5. the fact that, I am using custom jar which was created using hadoop 2.7.5. Is there any way to run that JAR on Amazon EMR? The cluster terminates with error each time I try to run that jar using existing EMR version (either with hadoop 2.7.3 or 2.8.3) which is logical.
