There are many other NoSQL databases  other than HBase like Cassandra, MongoDB, Couchbase.

All these databases use HDFS as a file system,these are built on top of Hadoop.

Apache Cassandra: Highly scalable, high performance distributed database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. 

Apache HBase: Open source, non-relational, distributed database modeled after Google’s BigTable and is written in Java. It is developed as part of Apache Software Foundation’s Apache Hadoop project and runs on top of HDFS (Hadoop Distributed File System), providing BigTable-like capabilities for Hadoop. 

MongoDB: Cross-platform document-oriented database system that eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas making the integration of data in certain types of applications easier and faster. 

Couchbase: Distributed NoSQL document-oriented database that is optimized for interactive applications.
