Adding user attribute after node has started

Hi,

1) Can we add/update user attribute after the node has started? 
2) If we want to run jobs using compute or start a cache on specific nodes
in the cluster then how can we do that?

Hi,

Node attributes can be added only before node startup.

To start a cache on specific nodes you could use
CacheConfiguration#setNodeFilter

Ignite#compute(org.apache.ignite.cluster.ClusterGroup) accepts a cluster
group which could be, for example ignite.cluster().forAttribute(...). 
As well, you could use IgniteCompute#affinityCall or
IgniteCompute#affinityRun.

Kind regards,
Alex
