------------
num_stream: To enhance the restore performance, you can configure the number of streams that each backup host can allow. Default value is 1.
additionalBackupHosts: To enhance the restore performance, you can configure additional backup host details. You can specify the hostname of additional backup hosts.
Notes:
You must keep
additionalBackupHostsempty, if no additional backup hosts are available.The
hadoop.confconfiguration must be same on all the backup hosts.The
num_streamconfiguration must be same for backup and restore process.Hadoop setups and NetBackup setups must be in the same timezone.
If you increase streams, adjust the maximum number of jobs per client, update the
stusetting for multiple threads, and update the client timeout to avoid abrupt failures.
