Nodemanagers fail to restart after adding Spark 2 Beta service. We have added the gateway role to all nodes and have the spark1 service installed. YARN ResourceManager and YARN History Server start fine but nodemanagers fail to start with the following error.
Role failed to start due to error com.cloudera.cmf.service.config.ConfigGenException

The Spark 2.0 Beta requires CM 5.8. Please install CM5.8 on your CDH5.7.1 cluster. Installing CM is a lightweight process. This error is likely because you are using CM5.7.
