Hadoop Versions and Distributions
Hadoop is an ecosystem of software providing various services related to distributed processing of data. One of these core services is HDFS ,which is a scalable and fault-tolerant distributed file system. If you want to run DataFlow in a distributed cluster, then we recommend that you use a distributed file system such as HDFS.
