Questions about mesos-storm
Hi List,
I found mesosphere has a good page
http://mesosphere.io/learn/run-storm-on-mesos/ to guide user setup a
mesos-storm cluster.
However, I found myself several questions about that guide.
1. Is it necessary to deploy storm nimbus on the mesos master node?
The guide only says about deploy storm nimbus on the mesos master node.
But I think it's fine to deploy storm nimbus on a different node. Am I
right?
2. How to deploy storm supervisor node?
The guide doesn't say anything about deploy supervisor node, from that
guide, I see superviosr node deploy on-demand when a topology submitted?
Does mesos-storm do such cool stuff?
If not, we need deploy supervisor in all mesos nodes?
--
Thanks,
Chengwei

"Thank you, I was thinking that it's generally OK to deploy a mesos
scheduler on a mesos slave node, regardless performance issue, say it
will communicate with mesos master frequently."
I would avoid launching the scheduler on a mesos slave since the scheduler
would run outside of Mesos jurisdiction (via cgroup), and may contend with
mesos tasks for resource. We have MesosNimbus running outside of the mesos
cluster, master or slave.

Thank you, I was thinking that it's generally OK to deploy a mesos
scheduler on a mesos slave node, regardless performance issue, say it
will communicate with mesos master frequently.

*"Yes, basically Nimbus runs as Mesos framework (inside Mesos master), if
Mesos master dies, it should start automatically on a different node.*
*It's not a standard Nimbus, it's MesosNimbus (Mesos framework):*
*code might look this (it's slightly outdated version):"*
This is actually not true. MesosNimbus works as a Mesos scheduler, which is
a client as seen by Mesos cluster. You can deploy it out side of the Mesos
cluster. However, it needs to have Mesos binary installed so that java can
load the native library.

Yes, I find that from source code. :-), apache is the most simplest one

Chengwei,
Rather than an internal http server, you could also point the
mesos.executor.uri to an ftp or hdfs uri if you prefer.

*supervisor.slots.ports: [6700 6701 6702 6703]*
You can remove supervisor.slot.ports from storm config. MesosNimbus uses
ports offered by Mesos infrastructure, which is independent of these ports.

This is confirmed, yes, supervisor started on-deman by storm-mesos.
When I exploring storm-mesos, I found some more questions.
I started storm-starter-0.0.1-SNAPSHOT.jar as a storm topology just like
the guide http://mesosphere.io/learn/run-storm-on-mesos/#step-9
And I do saw that topology start to run with only 1 supervsior, 1 worker.
However, I found something, maybe bugs, confused me.
1. The storm UI says the only supervsior provides *0* slots, why not the
default 4? I think below command says correctly, so this is a
storm-mesos bug?
# ./bin/storm remoteconfvalue supervisor.slots.ports
supervisor.slots.ports: [6700 6701 6702 6703]
2. As question 1, the default ports are [6700 6701 6702 6703]. However,
the started worker, the process name, says -Dworker.port=31000 in its
command line and the netstat also confirmed that. I see [31000-32000]
are DEFAULT_PORTS in mesos. I suspect this is used as -Dworker.port? Why
not one of [6700 6701 6702 6703]?
3. Even storm-mesos framework get killed, it still displayed as
*activate framework* in mesos web ui. I wait for several minutes and
didn't see any change.

Thank you, I saw that mesos.executor.uri set to the storm-mesos tarball,
however, my VM can not access external network, so I'll verify that by
setup a internal http server.

Hi Chengwei,
| 1. Is it necessary to deploy storm nimbus on the mesos master node?
Yes, basically Nimbus runs as Mesos framework (inside Mesos master), if
Mesos master dies, it should start automatically on a different node.
It's not a standard Nimbus, it's MesosNimbus (Mesos framework):
code might look this (it's slightly outdated version):
