Task

Description

After the NetBackup for Hadoop 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 NetBackup for Hadoop cluster.

Ensure that webhdfs service is enabled on the NetBackup for Hadoop cluster.

See Preparing the NetBackup for Hadoop cluster.

To establish a seamless communication between NetBackup for Hadoop clusters and NetBackup for successful backup and restore operations, you must add and update NetBackup for Hadoop credentials to NetBackup primary server.

Use tpconfig command to add NetBackup for Hadoop credentials in NetBackup primary server.

See Adding NetBackup for Hadoop credentials in NetBackup.

The backup hosts use the hadoop.conf file to save the configuration settings of the NetBackup for Hadoop plug-in. You need to create separate file for each backup host and copy it to /usr/openv/var/global/. You need to create the hadoop.conf file in JSON format.

With this release, the following plug-in settings can be configured

  • See Configuring NetBackup for a highly-available NetBackup for Hadoop cluster.

  • See Configuring number of threads for backup hosts.

Update the BigData policy with the original NameNode name.

See Create a BigData policy for Hadoop clusters.
