Be prepared for some service degradation ... 1. Reassigning regions to new node requires offlining regions (affects reads and writes) 2. Data locality on a new RS will be 0% from the beginning of operation (affects reads) 3. Your network traffic will increase because every compaction on a new node will access network for both: READ and WRITE (because you won't have store files locally)
