What's New in Apache HBase

This topic lists new features for Apache HBase in this release of Cloudera Runtime.

If you are upgrading from upgrading from HDP 2.x or CDH 5.x to CDP, you must review the pre-upgrade steps here: Preparing HBase for upgrade, and read about the Apache HBase API changes documented here: Deprecation Notices in Apache HBase.

HBase-Spark Connector

The HBase-Spark Connector bridges the gap between the simple HBase Key Value store and complex relational SQL queries and enables users to perform complex data analytics on top of HBase using Spark. For more information, see Using the HBase-Spark connector.

Store Medium Objects (MOBs)

Cloudera’s OpDB has a new feature called distributed MOB compaction. This feature overcomes a drawback of the older implementations of MOB compaction by moving maintenance of MOB data files from a centralized process handled by the HBase Master to a parallel process that is distributed across the RegionServers. For more information see, Storing Medium Objects (MOBs).
