about single service redistribution after node restart

[李奉先 <li...@gmail.com>]

My cluster has two nodes.When one of the
node(uuid:22ff0f84-9d6c-4b7f-9e71-8892c0dcc7fe)  is down and restarted, the
single service will not be redistributed  and only normal
nodes(uuid:d44abb38-b870-42c7-8c37-ca5e9cee3232)  exist.

I print service topologySnapshot
before one node(uuid:22ff0f84-9d6c-4b7f-9e71-8892c0dcc7fe)  reboot :

I hope the  single service can be redistributed in two nodes
How do I do it?

Hi!

Currently services don't get redistributed if new nodes join a topology.
So, if you have all services deployed on one node, then they won't be moved
to newly joined ones.
This is a known issue. The following ticket mentions it:
https://issues.apache.org/jira/browse/IGNITE-7667
Currently even distribution can be achieved by redeploying the services.
Also if you add the third node, and then kill the first one (containing all
the services), then the two nodes, that are left in the cluster, will host
an even number of services.
