Hadoop ecosystem is ptetty vast. I used the book "Haddop the definite guide" and "Hadoop Security". But I see more and more organizations moving to solutions that augment Hadoop (or even replace it) such as Apache Spark. I've never seen a customer yet that would prefer a classic map reduce job over a spark app after understanding the performance and developer productivity benefits. But I might just be lucky. AWS EMR is as others said a great place to get started and you can get Hadoop, Hive, Spark, Presto and other great projects easily installed and ready to go.
