What is the best way to do this? The cluster is currently being used for other tasks (Hive, Spark, etc) that I don't want to impact. Thanks, ... View more

You have to manually go into Ambari and tell the services to start on that host. What are some best practices and recommendations as to how to automatically bring up the hadoop services after an OS reboot? ... View more

Okay got the answer: For CentOS 6 and SLES 11: Hortonworks supporst Python 2.6.* (which is what is installed by default). Hortnworks do not support switching to Python 2.7.* on these OSs. For all other supported OSs (CentOS 7, Ubuntu 12 + 14, Debian 7): Hortonworks support Python 2.7.* (which is what is installed by default). As of Ambari 2.2, there is no longer an issue with 2.7.9 (therefore, you can use 2.7.*). ... View more
