Hadoop HDFS, SPARK Streaming,Scala

How to Start up on Hadoop HDFS and Spark Technologies? Any Online Learning resources for above techonolgies?where i can practice as these above are open sources? Any Suggestions?

There are online training websites for Big Data, but it’s important that you learn tools by practicing by yourself…
You can find the theoretical explanations online very easily, but the main thing is practicing on various datasets.
One good resource for this : “Learn Apache Spark 3 with Scala: Hands On with Big Data! | Udemy” https://www.udemy.com/course/apache-spark-with-scala-hands-on-with-big-data/
