Apache Kudu

It is compatible with most of the data processing frameworks in the Hadoop environment.

[4] The first version Apache Kudu 1.0 was released 19 September 2016.

[5] Kudu was designed and optimized for OLAP workloads.

Like HBase, it is a real-time store that supports key-indexed record lookup and mutation.

Kudu's "on-disk representation is truly columnar and follows an entirely different storage design than HBase/Bigtable".
