hadoop-services-0.1

Basic Hadoop service scripts for CentOS7/systemd and MacOS/launchd. The scripts are usable in principle (I am using them with a production Hadoop 2.7.7 cluster), but the installation procedure on MacOS leaves to be desired (you basically have to change the __*__ tokens manually to match your paths, copy them into /Library/LaunchDaemons/ and "launchctl load -w ..." them). Also, only hadoop-datanode and yarn-nodemanager are currently provided for MacOS.
