Hi Folks, Does anyone have idea regrading, start and stop services on all the nodes in parallel. i am facing an issue i have a big cluster like 1000 nodes and i want services to start and stop , if i do it sequentially it will take around 30-50mins , what can i do to make it parallelly, does anyone have any sample scripts for this thing.
i don't have passwordless connectivity, i nodes have same user and password. thanks hadoophive
