`config-tool activate -stripe <[name/]hostname[:port]|hostname[:port]|…>`

[mathieucarbou]

Allows to quickly activate a cluster when all nodes are already started with the right parameters

Examples:

config-tool -cluster-name tc-cluster -stripe node-1-1:9410|node-1-2,node-2-1:9410|node-2-2

config-tool -cluster-name tc-cluster -stripe node-1-1:9410|node-1-2 -stripe node-2-1:9410|node-2-2

config-tool -cluster-name tc-cluster -stripe stripe1/node-1-1:9410|node-1-2,stripe2/node-2-1:9410|node-2-2

Notes:

• the separator characters used (/ and |) are not a choice but more constrained coming from the set of characters that we do not allow to have in both hostnames and stripe names. Also , is already taken by JCommander to split parameter values.
• Nodes are expected to have the exact same cluster-wide settings , otherwise validation failure. It means the nodes have to be started, like in a cloud env, with similar cluster-wide settings but can have each one different node-specific settings
• Nodes have to be started with an empty topology (they should be alone)

@mobasherul : this is still in progress but 80% done. I just need to add some tests and verify the logic.

You can start reviewing in case you see something I missed in the logic ;-)

Thanks!

@mobasherul : finished adding a couple of tests. All works fine, PR ready to review and merge :-)
