Remote Dali access in AWS

Questions or comments related to Cloud Computing and the HPCC Systems Instant Cloud for AWS

Hi - I am running a Thor cluster and a Roxie cluster separately in AWS. After building the index in Thor, I would like to push it to Roxie by pointing to remote Dali. It errors out saying cannot connect to remote Dali. I have a few questions regarding that.
1. What is the protocol/port that is used to copy the data to a remote cluster.
2. Does the cluster need to have access to Dali or all the nodes and what kind of access.
3. Do I give the private IP or the public IP when connecting to Dali.

If there are any instructions to do it, that would be great too.

I've asked an HPCC architect to answer your question.

> 1. What is the protocol/port that is used to copy the data to a remote cluster.

By default Dali is on port 7070 (Tcp)

2. Does the cluster need to have access to Dali or all the nodes and what kind of access.

To access the parts on the Thor slaves, it will need access to dafilesrv on those slave nodes. That is listening on port 7100 (Tcp)

3. Do I give the private IP or the public IP when connecting to Dali.

That depends on how you've configured the cluster it's reading from.
By default it will bind to the 1st interface, but you can define which interface the setup uses by changing 'interface=*' in /etc/HPCCSystems/environment.conf to the specific interface you want, e.g. to 'interface=eth0'

Hope that helps.
