Yarn Active and Standby service have been stopped manually but can not be started manually in cloudera.
Could anyone please tell how to start Yarn Active and Standby Service manually?
Could you please explain more in detail? Are you facing any issues during startup? you can start it by selecting the instances on the Yarn instances page from the Cloudera manager
Cloudera manager --> Yarn --> instances --> Choose Active /Standby --> Click "Actions for selected" --> click the Start and it will help in starting the instances.
