Thor slave IP addresses

Post questions specific to installation or configuration for the HPCC Systems platform

Where does HPCC store the IP addresses of the Thor slave nodes.

Manually changing the environment.xml does not change the IP addresses of the thor slaves which continue to refer to the old IP addresses. At least this is what the files in /var/lib/HPCCSystems/mythor[uslave|uslave.start|thorgroup] and ECL Watch (see below) tell me. When you start thor, you can see that thor is trying to communicate to its slaves on the old IP addresses (calling start_slaves by ssh-ing to the old IP addresses).

When I go to the 'Target Clusters' view on ECL Watch, I can see that all components show the changed network addresses but thor slaves continue to show the old addresses. How do we change the network addresses for the Thor target cluster?

My HPCC version is 3.10.8-7.

Alight. So a bit of investigation reveals that these IP addresses are collected from dali through the 'daliadmin dfsgroup' command in the shell script run_thor. Now to find out how to remap these IP addresses in Dali.

Try forcing dali to update the environment with:

updtdalienv /etc/HPCCSystems/environment.xml -f

Yes, this did the trick. I can see the changed IP addresses in ECL watch now.

For completeness, the output from my command looked like:
Code: Select all
# /opt/HPCCSystems/bin/updtdalienv /etc/HPCCSystems/environment.xml -f
