Add shell a command that will batch move nodes from one cellar group to an other
--------------------------------------------------------------------------------
Key: KARAF-831
URL: https://issues.apache.org/jira/browse/KARAF-831
Project: Karaf
Issue Type: New Feature
Affects Versions: cellar-2.2.1, cellar-2.2.2
Reporter: Ioannis Canellos
Assignee: Ioannis Canellos
Fix For: cellar-3.0.0, cellar-2.2.3
In a large cellar cluster, its a pain to assign nodes to groups, because you
have to execute a cluster:group-set command on each node.
It would be really useful if there was a command that would allow the user to
move nodes from one group to an other in batches (and without having to specify
all node ids).
What I have in mind is a command say group-pick that will accept the source
group name, the destination group name and the number of node to move.
This command will select (the give number of) eligible nodes from the source
group and move them to the destination group.Eligible should be the nodes that
are only part of the source group and no other. In the oposite case the result
would be unpredictable and most possibly unwanted (if this is not clear I could
provide more details).
