Oozie installation is not stright forward similar to other applications. When I executed the mkdistro script, it failed with the below given error
./mkdistro.sh
./mkdistro.sh: line 71: mvn: command not found
Maven is a build tool for java, which is not instaled in my ubuntu VM. Hence we need to install it using the below given command to make the script working
hadoop@gandhari:~/oozie/bin$ sudo apt-get install maven
