      - Migrating between Apache HBase and HPE Ezmeral Data Fabric Database Binary Tables
        You can use the CopyTable tool to migrate data from an Apache HBase table to a HPE Ezmeral Data Fabric Database binary table.
      - Before You Start HBase Migration
      - Mapping to HBase Table Namespaces
        This section describes mapping table namespaces between Apache HBase tables and HPE Ezmeral Data Fabric Database binary tables.
      - Compression Mappings
      - Copying Data
      - Verifying Migration
      - Decommissioning Apache HBase Nodes
  - Application Migration
    Before you migrate your applications to the Data Fabric Hadoop distribution, consider testing your applications using a small subset of data.
  - Data Migration
    After you migrate your applications to the Data Fabric cluster, you can copy your data from the Apache Hadoop HDFS to the Data Fabric cluster.
  - Node Migration
    You can add decommissioned HDFS data nodes to your HPE Ezmeral Data Fabric cluster.
- Applying a Patch
  You can apply a patch by using the Installer, by using the command line (a manual process), or by using an Installer Stanza.

HBase Migration

The HPE Ezmeral Data Fabric Hadoop distribution includes HBase, with a number of Data Fabric-exclusive enhancements.

HBase is the Hadoop database, which provides random, real-time read/write access to very large datasets. The Data Fabric Hadoop distribution includes HBase and is fully integrated with Data Fabric enhancements for speed, usability, and dependability. Data Fabric provides a volume (normally mounted at /hbase) to store HBase data.

HBase bulk load jobs: If you are currently using HBase bulk load jobs to import data into the HDFS, make sure to load your data into a path under the /hbase volume.
Compression: The HBase write-ahead log (WAL) writes many tiny records, and compressing it would cause massive CPU load. Before using HBase, turn off Data Fabric compression for directories in the HBase volume.
