Restoring HBase data on an alternate HBase cluster

NetBackup lets you restore HBase data to another HMaster or HBase cluster. This type of restore method is also referred to as redirected restores.

Consider the following when you perform an alternate restore

  • To restoring HBase tables to different cluster, both cluster must have same HBase version deployed.

  • NetBackup supports redirected restores only using the Command Line Interface (CLI).

  • Make sure that you have added the credentials for the alternate HMaster or HBase cluster in NetBackup master server.

To perform redirected restore for HBase

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

    Parameter

    Value

    rename_file

    Change /<namespace:source_table_name> to /<namespace:destination_table_name> ALT_APPLICATION_SERVER=<alternate name node>

    listfile

    List of all the HBase files to be restored

    Note:

    /<namespace:source_table_name> and /<namespace:destination_table_name> must be different.

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

    Where,

    -S master_server

    Specifies the name of the NetBackup master server.

    -D backup_host

    Specifies the name of the backup host.

    -C client

    Specifies a HMaster 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 whitelisted 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_tablename to restore_tablename ALT_APPLICATION_SERVER=<Application Server Name>

    The file paths must start with / (slash).

    Note:

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