Installing ResourceManager
- Stop all services except for HDFS.
- Using the Ambari web client to manually stop each service.
- Using the Ambari REST APIs directly. For this method, you can consult the documentation on starting and stopping services.
Install ResourceManager manually Add a ResourceManager component to YARN on a host that does not already have ResourceManager installed. This will not actually install ResourceManager, but will setup the host component associations.
