Commodity hardware, sometimes known as off-the-shelf hardware, is a computer device or IT component that is relatively inexpensive, widely available and basically interchangeable with other hardware of its type. One may also ask, can NameNode and DataNode be a commodity hardware? One doesn’t require high-end hardware configuration or supercomputers to run Hadoop, it can be run on any commodity hardware. The commodity hardware comprises of RAM as it performs a number of services that require RAM for the execution. Spend the money you save on more servers. Correct! The location of Hive tables data in S3 or HDFS can be specified for both managed and external tables. Commodity clusters exploit the economy of scale of their mass-produced subsystems and components to deliver the best performance relative to cost in high performance computing for many user workloads. What does commodity Hardware in Hadoop world mean? The framework takes care of scheduling tasks, monitoring them and re-executing any failed tasks. Commodity hardware is a low-cost system identified by less-availability and low-quality. Regarding this, can Hadoop be deployed on commodity hardware?
