OK,
I'm probably being dense here.
(There's only 1 context in each host, the ROOT context)
If I take the Host/Context offline in one node and restart it, the logs
on that node start showing the following:
SEVERE: Context manager doesn't exist:host1
As the Context doesn't exist, which is the same message that appears
briefly in the logs during a restart, until that particular Host is
loaded (under normal circumstances).
This much I understand, and provides no problems for me.
With all Hosts available on each node of the cluster, I then update the
Context on one Host, (by adding a new jar, say). The Context has
reloadable="true", so it does just that.
Once that context has updated, the other nodes start seeing:
SEVERE: Context manager doesn't exist:host1host1
If I reload the context again, (without restarting the server), I see this:
SEVERE: Context manager doesn't exist:host1host1host1
I could go on, but I think you can see where this is going...
