1. Simplify config.yaml to have 3 set of configuration:
a. HPCC package version and checksum
b. SSH Keys
c. HPCC components configratation (thor/roxie)
2. Re-implement config-changed hook
a. Update HPCC package. HPCC has related short release cycle.
Usually every 2-3 months there is a new/update release.
User can update HPCC package by:
juju set <hpcc service> hpcc-version=<new version> package-checksum=<checksum>
b. Update SSH Keys
juju set <hpcc service> ssh-key-public=<new key> ssh-key-private=<new key>
c. Update HPCC cluster topology:
juju set <hpcc service> thor-ratio=<new ratio> roxie-ratio=<new ratio>
The ratio is based on compute nodes which is <number of unit node> minus
<support node>.
4. Make the scripts under hpcc/bin optinal. There is a readme which tell the purpose
of these scripts
5. We still support juju local provider
But due to the problem reported in launchpad bug 1288969 it can run multiple roxie
nodes in lxc environment. If users want launch multiple nodes they need set
roxie-ratio to 0 in config.yaml.
New fixes are submitted to lp:~xwang2713/precise/hpcc/turnk and lp:~xwang2713/trusty/hpcc/turnk
The only difference between these two are the config.yaml and README.md
Here are the commit message:
Re-implement to make configuration not immutable
