Re: how differences between hadoop and apache flink?
I'm quoting Chiwan Parks answer to this question:
Hadoop is a framework for reliable, scalable, distributed computing. So,
there are many components for this purpose such as HDFS, YARN and
Hadoop MapReduce. Flink is an alternative to Hadoop MapReduce component.
It has also some tools to make map-reduce program and extends it to
support many operations.
You can see more detail description in Flinkās Homepage[1]
