Next year’s IoT expansion will roughly double traffic-sensor volume on the municipal lake. How does a Hadoop cluster typically grow capacity?
Select an answer to reveal the explanation.
Short Explanation
When the library needs more capacity, roll in more shelving units instead of one mega-drawer. Hadoop grows by adding nodes—more DataNodes and workers for next year’s IoT flood. Vertical-only tricks and single-disk fantasies miss that scale-out story.
Full Explanation
Hadoop clusters are designed for horizontal scale-out: adding nodes increases aggregate storage and compute capacity. That model fits municipal IoT growth better than forcing all data onto one disk or into NameNode memory. Format changes alone do not replace the need for additional cluster capacity.
