  - Installing HBase
  - Upgrading HBase
    - Preparing a Node for an HBase Upgrade from 0.94
      When you upgrade from HBase 0.94 to HBase 0.98 or 1.1, you need a node in your existing cluster that is not running HBase 0.94 but has connectivity to ZooKeeper and MFS services on the cluster. The following instructions explain how to workaround this issue by preparing an existing node that is running HBase for the upgrade. You cannot add a node to the cluster to serve this purpose.
    - Upgrade from HBase 0.94.x
      Complete the following steps to upgrade HBase 0.94.x to HBase 0.98.12 or 1.1.

4. Back Up Configuration Files

If you have changed configuration properties on your current installation of HBase, you probably want to apply those changes to the updated version. Configuration properties are located in

/opt/mapr/hbase/hbase-<version>/conf/

Create a backup of any configuration files that contains customized values.
