----------------------------------------
This is not a HDFS bug. Please use user@hadoop for questions like this.
That said, please check your firewall configuration, make sure connections can
be made across the network without problem.
For distcp, you will need to specify the cluster NameNodes and logical service
id in core-site.xml / hdfs-site.xml
> distcp geo hdfs site is not working

> 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
