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.

On the other hand, Hadoop does have HBase, which is their version of Bigtable. It was, for a number of years, a very popular columnar K/V store.
Hadoop and Bigtable are not the same thing. Bigtable is a noSQL database. Hadoop is a big data processing framework. Hadoop is actually an open source implementation of MapReduce, which was developed at Google and which has since been replaced by Flume
