Does Hadoop works on Parallelism mechanism.
According to popular articles, Hadoop uses the concept of parallelism to upload the split data while fulfilling the “Velocity” problem.
Monitor port 50010 for data transfer.
As soon as we put data, we see that DataNode 3 receives data first.
Once this ends, we see that transfer starts to other DataNode 1.
Hence proved that data upload does not happen parallelly.
