About Apache Storm. Direct use of the HBase API, along with coprocessors and custom filters, results in performance on the order of milliseconds for small queries, or seconds for tens of millions of rows. More information can be found here. Tables are stored in a flat It writes data from a topic in Kafka to a table in the specified HBase instance. The HBase connector offers the most natural way to connect to integrate with HBase data, and provides additional powerful features.

Convenient base classes for backing Hadoop MapReduce jobs with Apache HBase tables. It seems like a lot of extra space overhead and coding overhead (to keep them in sync) to support 2 tables. The interpreter assumes that Apache HBase client software has been installed and it can connect to the Apache HBase cluster from the machine on where Apache Zeppelin is installed. The following sample uses Apache HBase APIs to create a table and put a row into that table. A Ecosystem Pack (MEP) provides a set of ecosystem components that work together on one or more MapR cluster versions.
