Re: mesos ui best practise - mesos cluster in HA

[Jeremy Olexa]

This is what we use in haproxy:

backend master_cluster
  option httpclose
  option forwardfor
  mode http
  option httpchk GET /metrics/snapshot
  http-check expect string master\/elected":1
  server master-0 ip1:5050 check
  server master-1 ip2:5050 check
  server master-2 ip3:5050 check

Hope it helps,
Jeremy

You can check which is the current master by looking for the number of
active slaves in state.json; if it's not zero, then the node is the
current master. I'm away from a computer atm, but I can provide a full
haproxy health check config if that'd be useful.

That said, it'd be really great if we could get a /is_master endpoint
or something for this use; trying to do this with nginx has driven me
to the brink of madness.

There's really no use mesos-dns and just point your browser to
http://leader.mesos:5050 to reach the active master.

mesos ui best practise - mesos cluster in HA

[Haripriya Ayyalasomayajula]

Hi all,

I am having a mesos cluster  (version 0.25.0) running in with 3 masters. I
am getting back to the community regarding the best practise that can be
adopted.

-I want to access the UI from a login node. How can I use haproxy in this
case? I have the following HAProxy configuration file on the login node
which has access to the three nodes running masters (servers with ip1, ip2,
ip3).

#-

# Proxy for the mesos-master console

#-


listen mesos-master 0.0.0.0:5050

mode http

option forwardfor



server server1 ip1:5050 check

server server2 ip2:5050 check

server server3 ip3:5050 check

I'd greatly appreciate any inputs here.

Thanks!

Marathon Issue filed.

At this point, should I look at a Mesos JIRA too?

Re: Web UI Memory Usage in Firefox

[Joseph Wu]

Hi John,

I wonder if this is just an issue with how Firefox does garbage collection.

Can you try navigating to about:memory and clicking the "GC" button?  The
web UI's definitely should not need that much memory.

Web UI Memory Usage in Firefox

[John Omernik]

I am cross posting this in Marathon and Mesos lists because both UIs are
having this issue, and I figured I'd save time in posting two separate
messages.

Basically, in using Firefox, I noticed that over time, my firefox would get
to become unusable when I had Marathon and Mesos WebUIs up and running.  At
first, I thought it was a function of my home (Mac) computer and firefox.
But when I started a PoC for work, and my Windows install of firefox had
the same issues, I started doing more investigation.

First of all, both at home and at work, my Firefox is only dedicated to
"cluster" related tasks. Thus, I don't have other tabs that are not Cluster
UIs.

My typical setup is to have MapR UI, Mesos UI, Marathon UI, Chronos UI,
Myriad UI, and Yarn UI all up and running.

After about 3-4 hours, my browser would get really slow, and
non-responsive. I'd kill all and start again.  Rinse repeat.

So I did some analysis, and basically found a plugin for Firefox that shows
on each tab the amount of memory being used. I found that both Marathon and
Mesos UI were the culprits, and things got really bad after just 2-3
hours.  With those setup, on Windows, I have the following memory usage:

MapR UI: 7.7mb
Myriad UI: 9.8mb
Yarn: 2.7 mb
Chronos 10.2 mb
Marathon: 163 mb
Mesos UI: 463 mb

Both Marathon and Mesos continually climb, slowly, up some, down a few, up
some more, but obviously generally trending up.  I guess I wanted to toss
it out here to see if it's something in my settings, or something that
others are seeing.  It's a problem for me from a usability standpoint, and
I am guessing that it's one of those things that while not a priority for a
project, should be looked at.

RE: Roles and Oversubscription

[Plotka, Bartlomiej]

Hi John,

As you can see here: 
https://github.com/apache/mesos/blob/master/docs/oversubscription.md#launching-tasks-using-revocable-resources
… “revocable” is only an additional attribute in Mesos Resource. So you can 
specify the roles independently of revocable on/off.

For example you could specify some revocable resources in Fixed Resource 
Estimator for role “example”:
--resource_estimator="org_apache_mesos_FixedResourceEstimator"

--modules='{
  "libraries": {
"file": "/usr/local/lib64/libfixed_resource_estimator.so",
"modules": {
  "name": "org_apache_mesos_FixedResourceEstimator",
  "parameters": {
"key": "resources",
"value": "cpus(example):14"
  }
}
  }
}'
As a result frameworks with this role can access these.

Feel free to ask if anything else need to be explained.

Kind Regards,
Bartek Plotka (bplotka)

Subject: Roles and Oversubscription

How do roles and oversubscription work together?  When you specify resources 
that can be oversubscribed, do you say what role they work in? Is "revocable" a 
role in and of itself?

I am trying to work through these various items in my path to learning more 
about oversubscription.

Thanks!

John

Sync Mesos-Master to Slaves

[Frederic LE BRIS]

Hi,

I manage a Mesos Cluster 0.23.0 based on .deb from Mesosphere on Ubuntu 14.04.

We deployed 3 zookeeper, 3 Mesos-master, and 3 Marathon : HA Mode

And deployed 6 mesos slaves + slave process on 3 masters mesos.

So I have the following topology:

3 servers : Mesos-master / Marathon
3 servers : Zookeeper / mesos-slaves.
3 servers : mesos-slave

I follow the HA configuration for Mesos-master and marathon.

The point is when I kill the leader mesos-master, we lost the existing task on 
the slave, and the ressources available are lock by the slave even if the 
master see no activity on this slave.

My mesos cluster is in production, so I’m not able te restart from scratch, so 
I look for a procedure te re-synchronise the cluster.

And some way to check that my leaders mesos master are working together as a 
leader and two slaves correctly synchronize.

I guess I miss something, but I’m need some help...

Regards,

Fred

Re: [VOTE] Release Apache Mesos 0.26.0 (rc3)

[Jan Schlicht]

+1 (non-binding)

Tested OS X, CentOS 7.1 and Fedora 23.

Ran `sudo ./bin/mesos-tests.sh` on CentOS 7.1 and Fedora 23 with SSL
disabled as well as enabled. Had to disable "perf"-related tests, because
"perf" doesn't work in my virtual machines. All tests passed, but some were
flaky: For these, JIRA tickets exist and they are known test bugs.
`./bin/mesos-tests.sh` was fine with OS X.

`make check -j7` — OK
`make distcheck -j7` — fails, probably MESOS-3973
, see hints below.

Both on Mac OS 10.10.4

I see the following lines in the log:
