Distcp firewall rules

New Contributor


I need to move data between PROD and DEV clusters with same HDP version and HA.

Prod = 8 DNs

DEV = 4 DNs

I would like to use distcp. What firewall rules do I need to setup?

My assumption:

1. Allow port 50010 from each Prod DN to each Dev DN - 32 rules.

2. Allow port 8020 from for active Prod NN to active Dev NN -1 rule.

3. Execute discp on Prod cluster

My questions:

1.Do I need to apply FW rules also in opposite way - from Dev to Prod?

2. Any idea to simplify this process - performance is not so important goal is to move data from hdfs to hdfs

Thanks in advance,
