Where are hadoop jar files in hadoop 2? [closed]
Actually, I faced a similar issue in the beginning. Apparently, there is no hadoop-core.jar for version 2. You'll have to download the Hadoop Common and MapReduce Client Core jars and use them both. I am sure it'll solve your problems. Hope this helps!
Edit: I just updated the links such that people can choose the appropriate version from the repository since we now come way past the initial version 2.
