Change project.clj sample for new Hadoop dependencies

[ikarius]

The sample file 'project.clj' still shows old Hadoop dependencies.

The new and working ones (replace 2.7.3 version with your Hadoop version):

  :profiles {
             :provided {:dependencies [[org.apache.hadoop/hadoop-common "2.7.3"]
                                       [org.apache.hadoop/hadoop-hdfs "2.7.3"]
                                       [org.apache.hadoop/hadoop-mapreduce-client-core "2.7.3"]
                                       [org.apache.hadoop/hadoop-mapreduce-client-jobclient "2.7.3"]]}
             :uberjar {:aot :all}
             }
