Hadoop is a collection of things: HDFS (filesystem), Hbase (keyvalue database), MapReduce (data processing), and YARN (resource scheduling and job management).
Hbase was open-source implementation of Bigtable while HDFS was a copy of Google File System. The divergence appeared with other processing frameworks like Spark but now there's Apache Beam to unify it all.
