To perform redirected restore for Hadoop

1. Modify the values for rename_file and listfile as follows:

   Parameter	Value
   rename_file	Change /<source_folder_path> to /<destination_folder_path> ALT_APPLICATION_SERVER=<alternate name node>
   listfile	List of all the Hadoop files to be restored

2. Run the bprestore -S primary_server -D backup_host -C client -R rename_file -t 44 -L progress log -f listfile command on the NetBackup primary server using the modified values for the mentioned parameters in step 1.

   Where,

   -S primary_server

   Specifies the name of the NetBackup primary server.

   -D backup host

   Specifies the name of the backup host.

   -C client

   Specifies a NameNode as a source to use for finding backups or archives from which to restore files. This name must be as it appears in the NetBackup catalog.

   -f listfile

   Specifies a file (listfile) that contains a list of files to be restored and can be used instead of the file names option. In listfile, list each file path must be on a separate line.

   -L progress_log

   Specifies the name of allowlisted file path in which to write progress information.

   -t 44

   Specifies BigData as the policy type.

   -R rename_file

   Specifies the name of a file with name changes for alternate-path restores.

   Use the following form for entries in the rename file:

   change backup_filepath to restore_filepath ALT_APPLICATION_SERVER=<Application Server Name>

   The file paths must start with / (slash).

   Note:

   Ensure that you have allowlisted all the file paths such as <rename_file_path>, <progress_log_path> that are already not included as a part of NetBackup install path.
