Configuring the Daemons to Start on Boot
ImportantMake sure you are not trying to run MRv1 and YARN on the same set of nodes at the same time. This is not recommended; it will degrade your performance and may result in an unstable MapReduce cluster deployment.
To start the Hadoop daemons at boot time and on restarts, enable their init scripts on the systems on which the services will run, using the chkconfig tool. See Configuring init to Start Core Hadoop System Services.
Non-core services can also be started at boot time; after you install the non-core components, see Configuring init to Start Non-core Hadoop System Services for instructions.
