worker.properties misconfiguration ?
Hi,
I came across this worker.properties that has two workers to
balance the load.
worker.list=node1,node2 loadbalancer,status
This particular line seems to be misconfigured. 'worker.list' has
node1,node2 <space> loadbalancer,status
I think the line should be like this
worker.list=loadbalancer,status
Does anyone know if the incorrectly configured line is actually meaningful
?
Thanks,
Mohan

It does have an effect according to the netstat output.
I want to forget this configuration in a production bank server done by
someone :-) It looks like the parser picked up node1, They have ignored
the parser errors wherever it is logged.
node2 loadbalancer is not a node at all. A space is there instead of a
comma. But node2's AJP port is connected to from the Apache machine and I
don't
know if I have to suspect the 'status' worker or not.
I am changing everything.
Thanks.

Well, that line does have an effect... just not the likely intended
effect.
What you will probably end up with is three actually-active workers:
"node1", "node2 loadbanalcer" and "status".
Since you have configured a "status" worker, try navigating to
whatever URL has mounted that worker (or add a JkMount that does such
a thing) and looking at the effective configuration.
I'm surprised you didn't get an error on this line:
>> worker.loadbalancer.balance_workers=node1,node2
...since "node2" probably does not exist.
