    This section describes how to migrate customized components to Hadoop for the HPE Ezmeral Data Fabric.
    - Hive Migration
      You can continue to use Hive tables in a MapR cluster.
    - HBase Migration
      The MapR Hadoop distribution includes HBase, with a number of MapR-exclusive enhancements.
      - 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.

      - Copying Data
      - Verifying Migration
      - Decommissioning Apache HBase Nodes
  - Application Migration
    Before you migrate your applications to the MapR Hadoop distribution, consider testing your applications using a small subset of data.
  - Data Migration
    After you migrate your applications to the MapR cluster, you can copy your data from the Apache Hadoop HDFS to the MapR cluster.
  - Node Migration
    You can add decommissioned HDFS data nodes to your MapR 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.

Decommissioning Apache HBase Nodes

About this task

To decommission nodes running Apache HBase, follow these steps for each node:

Procedure

From the HBase shell, disable the Region Load Balancer by setting the value of balance_switch to false:
```
hbase(main):001:0> balance_switch false
```
Leave the HBase shell by typing exit.
Run the graceful stop script to stop the HBase RegionServer:
WARNING The graceful_stop.sh script does not look up the hostname for an IP number. Do not pass an IP number to the script. Check the list of RegionServers in the Apache HBase Master UI to determine the hostname for the node being decommissioned.
```
[user@host] cd /opt/mapr/hbase/hbase-<hbase-version>
./bin/graceful_stop.sh <hostname>
```
