Description

I am facing some issues in deploying HDFS at docker swarm network across geo sites.

“distcp” command which is running at a HDFS datanodes container is not able to pull the data from one site to another site(which is set to run at another docker swarm network). It expects the docker swarm, HDFS datanodes to be in host network configuration other than overlay(with ip forwarding), bridge network.

We want to know how the shipment of docker based HDFS deployment would look like, how distcp command would get invoked across docker instances sitting at different Geo’s
