# This is a live-testing script for most/all of the htools

# programs. It needs either to run on a live cluster or access to a

# cluster via ssh and an exported LUXI interface (via socat, for

# example). The cluster must not be empty (otherwise the hail relocate

# test will fail).

# Use: if running on a cluster master, just running it should be

# enough. If running remotely, set env vars as follows: LUXI to the

# export unix socket, RAPI to the cluster IP, CLUSTER to the command

# used to login on the cluster (e.g. CLUSTER="ssh root@cluster"). Note

# that when run against a multi-group cluster, the GROUP variable

# should be set to one of the groups (some operations work only on one

# group)
