@Vigneshraja Palaniraj​  Sure Vignesh . Thanks a for your review and inputs. let me try this. Currently shared cluster is used by users and need to plan in sometime where jobs are not planned to align it to single node memory one. Any suggestable memory instance will suite here based on your experience?

Coming to installment table it is around 32Gb and i am wondering that ordering will take how long. I will add it my list of tasks to perform and see as option.
