Tuning replication policy (advanced options)
Specify bandwidth per map, in MBps. Each map is restricted to consume only the specified bandwidth. This is not always exact. The map throttles back its bandwidth consumption during a copy in such a way that the net bandwidth used tends towards the specified value.
If you are using Capacity Scheduler queues to limit resource consumption, enter the name of the YARN queue for the cluster to which the replication job will be submitted.
You can adjust this setting so that each map task is throttled to consume only the specified bandwidth so that the net bandwidth used tends towards the specified value. The default value for the bandwidth is 100 MB per second.
Use this option to set the maximum number of map tasks (simultaneous copies) per replication job.
The Advanced Settings attributes are applied only during DLM replication jobs that are based on DistCp functionality.
