Task	Description
After the HBase cluster and nodes are up, prepare the cluster for operations with NetBackup.	Perform the following tasks: Update firewall settings so that the backup hosts can communicate with the HBase cluster. Ensure that webhbase service is enabled on the HBase cluster. See Preparing the HBase cluster.
To establish a seamless communication between HBase clusters and NetBackup for successful backup and restore operations, you must add and update HBase credentials to NetBackup master server.	Use tpconfig command to add HBase credentials in NetBackup master server. See Adding HBase credentials in NetBackup.
The backup hosts use the `HBase.conf` file to save the configuration settings of the HBase plug-in. You need to create separate file for each backup host and copy it to `/usr/openv/netbackup/`. You need to create the `HBase.conf` file in JSON format.	With this release, the following plug-in settings can be configured See Configuring NetBackup for a highly-available HBase cluster.
Update the BigData policy with the original HMaster name.	See Configuring NetBackup policies for HBase plug-in.
