If we have submitted one job and later we want to increase some resources to that jobs so can we do that ?
I found following thread was opened long back but checking if we some way to achieve this .
There are certain things which we reset when executing a job. If it is in Hive then the following may work
But if you are talking about resource allocation like increasing the size of a queue then I dont think that achievable on the fly when executing a job. Below link might help
You can use the queue setting to move your application from low resource queue to high resource queue while the job is running. Use "yarn application -movetoqueue" command. Also you can use the ambari to allocate high % of resource to any given queue.
