Re: Mesos 0.28.2 does not start

[Stefano Bianchi]

sorry i have made a mistakee in my previous message,
On each master: nano /etc/zookeeper/conf/zoo.cfg
the last three lines are:
server.1=192.168.100.3:2888:3888
server.2=192.168.100.4:2888:3888
server.3=192.168.10.3:2888:3888

these are the correct IPs i have set in this file.

Re: Mesos 0.28.2 does not start

[Stefano Bianchi]

I have set:

1)
On master1:
sudo -u zookeeper zookeeper-server-initialize --myid=1

On Master2:
sudo -u zookeeper zookeeper-server-initialize --myid=2

On Master3:
sudo -u zookeeper zookeeper-server-initialize --myid=3

i checked /var/lib/zookeeper/myid and i get correctly 1, 2 and 3


2) On each master: nano /etc/zookeeper/conf/zoo.cfg
the last three lines are:
server.1=192.168.100.54:2888:3888
server.2=192.168.100.55:2888:3888
server.3=192.168.10.16:2888:3888

where 2888 and 3888 are both open on openstack security group.

3)nano /etc/mesos/zk

zk://192.168.100.3:2181,192.168.100.4:2181,192.168.10.3:2181/mesos

4) Set the quorum to 2with
nano /etc/mesos-master/quorum  and i have written 2

5)then in /etc/mesos-master/ i created hostname and ip files, within which
i have written the public IPs of the masters such that i can use sandbox on
web ui.
the same in /etc/marathon/conf/ just creating hostname file.

let me say that the openstack cluster on which i'm now working on isnot on
the public internet but under a private network of the university lab.

Actually i don't have the access to the Mesos UI so i need to find the log
within CentOS VM.
Please can you tell me where can i find the master log file ?

Mesos 0.28.2 does not start

[Stefano Bianchi]

Hi all
i'm re installing my platform on another openstack tenant.
I downloaded all the needed softwares, zookeeper-server, mesos 0.28.2
marathon 1.1.1 and chronos 2.4.0.
i have configured all correctly the i started zookeeper-server and it works
fine.
when i type: service mesos-master start
it seems to start but if i check the status with: service mesos-master
status
i obtain the following:

[root@master ~]# service mesos-master status

Redirecting to /bin/systemctl status  mesos-master.service

● mesos-master.service - Mesos Master

   Loaded: loaded (/usr/lib/systemd/system/mesos-master.service; enabled;
vendor preset: disabled)

   Active: activating (auto-restart) (Result: signal) since ven 2016-06-10
15:39:36 UTC; 3s ago

  Process: 12163 ExecStart=/usr/bin/mesos-init-wrapper master *(code=killed,
signal=ABRT)*

 Main PID: 12163 (code=killed, signal=ABRT)


Any one knows why i have this issue?

Thanks in advance.

Re: Mesos and Openstack

[Stefano Bianchi]

Yes, you should also edit the hosts file where you associate the hostnames
of each VM to the correspondent private IP address.

Re: How to install marathon-lb

[Stefano Bianchi]

Hi kamil

I tried to replace that hostname with the one related to one random slave.
And it does not work.
I tried also to change the private IP od the marathon instance with the
public, but i still have problem.
I'm also running Mesos-DNS this should be a problem?

where:

131.154.96.27: is the hostname i set in /etc/mesos-master/hostname and
/etc/mesos-master/ip files.

Re: setting roles in mesos 0.28

[Stefano Bianchi]

I notice from mates of mine, several issues with mesos 0.28.1. Specially on
the master election stability. When a master is elected, after a minute it
disconnect re-electing another master.
Anyone of you have this issue?
This is not my issue, since im running 0.27.2 which is much more stable.

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

Since i already mentioned, anyone of you tried to run hadoop as docker
container from marathon?
i tried with this simple json:

{

  "id": "hadoop",

  "cpus": 1,

  "mem": 1000,

  "container": {

"type": "DOCKER",

"docker": {

  "image": "sequenceiq/hadoop-docker:2.7.1",

  "network": "HOST"

}

  }

}

the app appears as running but the bar is yellow and on mesos i see staged.
The container is more or less 800 MB probably i need to wait that pull
operation ends? Maybe the i need to give more ram and also some storage?

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

Thank you Guillermo Rodriguez
I will try your solution as soon as possible since wordpress is not the
goal task i wanna run, it was just an example to understand how to launch a
docker container, and of course i have chosen the easiest one :P
However, i correctly run Jenkins, Jupyter and Owncloud, now i'm trying to
do the same with hadoop.
Thanks to all guys.

RE: Launch docker container from Marathon UI

[Stefano Bianchi]

Hi Aaron
Actually both mesos-dns and calico are running even though these containers
im running are not, yet, using the calico ipaddr specific in json
description.
So i guess it is a problem of bridging, i guess simply specify HOST option
on container field in Marathon UI

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

Thanks *Rad* Gruchalski, actually i'm trying to make a json file that
"translate" this command in marathon:

docker run --name some-wordpress --link some-mysql:mysql -d wordpress

i guess the error is relate to the fact that i'm not specifying --link
some-mysql:mysql
My problem is that i don't know how to do that, i tried to fill environment
variable fields:

Key = link
Value = some-mysql:mysql

But in this way the app does not work as well. How can i configure these
env variables?

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

jupyter is working fine.
i tried to run wordpress and i get this error in stderr of mesos:

error: missing WORDPRESS_DB_HOST and MYSQL_PORT_3306_TCP environment
variables

  Did you forget to --link some_mysql_container:mysql or set an external db

  with -e WORDPRESS_DB_HOST=hostname:port?



Some one of you know this issue?

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

June i tried to run your json, but the task is waiting, and if starts it
failed immediately.

I guess because i did not type this commands:


   1.

   echo 'docker,mesos' > /etc/mesos-slave/containerizers

   2.

   $ echo '5mins' > /etc/mesos-slave/executor_registration_timeout


Could it be the problem?

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

thanks haosdent.
actually i have run this kind of apps through rest api.
Now i want learn how to laung docker files. I found this exaple:

{
  "container": {
"type": "DOCKER",
"docker": {
  "network": "HOST",
  "image": "group/image"
},
"volumes": [
  {
"containerPath": "/etc/a",
"hostPath": "/var/data/a",
"mode": "RO"
  },
  {
"containerPath": "/etc/b",
"hostPath": "/var/data/b",
"mode": "RW"
  }
]
  }}


I am able to link the correspondent field in the marathon UI with what is
written in this json.
What i need to understand is, what i should write in:

 "image": "group/image"

i mean, with what i have to replace group and image?
For instance, if i would run wordpress container on docker hub what i
should put replacing "group/image" ?

List of possible mesos tasks to run

[Stefano Bianchi]

I guys.
I have finally deployed my disttibuted mesos cluster. Of course im on
openstack and it is a simplified view of a real distributing cluster,
however mesos is able to disttibute tasks ok different networks.
Now i need to test come long running applications that can be launched from
marathon. I mean something that is visually viewable from my web browser.
I am not so aware of these apps do i would ask to you soke suggestions.
My department would like, for instance, run hadoop, i mean from marathon
launch hadoop which will be allocated to a certain slave. Is it possible? I
m open to other sugvestions.

Best regards and thanks  to all of you

Re: removed slace "ID": (131.154.96.172): health check timed out

[Stefano Bianchi]

Now it seems working.
I guess for 2 reasons:
1) I set up /etc/mesos-master/ip and etc/mesos-slave/ip thanks for your
suggestion.
2) i added in the routing table the gateway to reach the other network.
the second point continue to be strange, since only for 3 machines i had to
place the routing rule, while for other machine there were not necessary.
However, now i have 2 mesos masters on network 1 and 1 mesos master on
network 2 connected each other, and all the slaves are connected to the
leader without disconnecting.
Thanks a lot guys if i have other issues i will share with you!

However i have omitted to say that on these machines is running docker, on
some machines docker is running a service on other dont, i saw the docker

Actualli the majority of these settings i have already done, out of
/etc/mesos-master/ip, here should i write the ip of master interface ? And
/etc/mesos-slave/ip, here i should write the ip of slave interface ?
Your suggest seems the right one, because if i try to ping some machines
from a network to another someone is reachable some other don't, and these
latters sometimes, commonly at boot, are able to ping and aftwr a while
dont.
Thanks for your suggestion i m going to try.

Hi Dick Davies

Could you please share your solution?
How did you set up mesos/Zookeeper to interconnect masters and slaves among
networks?

Thanks a lot!

Re: removed slace "ID": (131.154.96.172): health check timed out

[Stefano Bianchi]

Indeed, i dont know why, i am not able to reach all the machines from a
network to the other, just some machines can interconnect with some others
among the networks.
On mesos i see that all the slaves at a certain time are all connected,
then disconnected and after a while connected again, it seems like they are
able to connect for a while.
However is an openstack issue i guess.

Does this also happen when master3 is leading? My guess is that you're not
allowong incoming connections from master1 and master2 to slave3.
Generally, masters should be able to connect to slaves, not just respond to
their requests.

Hi
On openstack i plugged two virtual networks to the same virtual router so
that the hosts on the 2 networks can communicate each other.
this is my topology:

---internet---
|
   Router1
|

| |
Net1Net2
Master1 Master2 Master3
Slave1 slave2  Slave3

I have set zookeeper in with this line:

zk://Master1_IP:2181,Master2_IP:2181,Master3_IP:2181/mesos

The 3 masters, even though on 2 separated networks, elect the leader
correclty.
Now i have started the slaves, and in a first time i see all 3 correctly
registered, but after a while the slave 3, independently form who is the
master, disconnects.
I saw in the log and i get the message in the object.
Can you help me to solve this problem?


Thanks to all.

Re: Mesos Clusters on different Network

Maybe i found a solution is an openstack isshe.
Probably i need jus to use the same virtual router for both netwoks.
I will keep you updated

Mesos Clusters on different Network

[Stefano Bianchi]

Hi

I already asked this question but idecided to open a new topic since where
i wrote before were not the correspondent topic.

So, as many of you have already understood, i'm working on openstack, where
there is not a DNS.
I have made 2 networks, NetA and NetB, on each of them there is a mesos
cluster.
I would like to connect them, im using zookeeper for the masters
coordination and slaves registratuons.
My question is, if i have a DNS which make all the machines on NetA and
NetB communicating each other, pinging them or telnet or ssh, configuring
zookeeper files with private IP can i reach the condition of distributed
mesos clusters?

Unfortunately in the openstack environment where i am working there is not

And this miss it's causing me a lot a issues also for other stuff.

Re: Mesos Masters Leader Keeps Fluctuating

[Stefano Bianchi]

Ok please follow me in this strange story.
At the beginning i have set 3 mesos master on the same cluster using mesos
0.27
now i deleted one of these 3 mesos 0.27 masters and build a mesos 0.28 to
joint to the other 2.
I get the problem i described after 10 seconds i get failed to connect, but
the election of new one works fine because the new leader is 0.27 which is
stable.
How to send to you logs?

Mesos-DNS Failed to connect to...

[Stefano Bianchi]

Im correctly running mesos-dns from marathon and it seems to work.
But when i launch:

http://test.marathon.mesos

(where test is a funning task on marathon)

I get:

curl: (7) Failed connect to test.marathon.mesos:80; Connection refused

Where am i wrong?

Re: Mesos Master and Slave on same server?

[Stefano Bianchi]

I have set an HA cluster.
3 mesos slaves with one leader and quorum 2.
3 mesos slaves.
I can easily start tasks from marathon.
The common way is set the slaves on other machines.
However if you are running the mesos-slave service also on the master is it
not a problem.

Re: Mesos interconnection among clusters project calico

[Stefano Bianchi]

June Taylor, is there another channel on which i can contact you?
Since i am a simple student doing his master thesis on mesos/calico, i need
all the support possible :P
I already have of course from my supervisor and advisor, but sometimes is
better have discussions with more skilled people.

Re: Mesos interconnection among clusters project calico

[Stefano Bianchi]

Thanks to your reply June.

You mean this feature?
https://coreos.com/etcd/docs/latest/clustering.html
Because for sure i know that calico exploit etcd as datastore, but i need
to know if, and if yes how, i can manage etcd as DNS.

Re: Mesos Master and Slave on same server?

[Stefano Bianchi]

For sure it is possible.
Simply Mesos-master will the the resources offered by the machine on which
is running mesos-slave also, transparently.

Re: Mesos Masters Leader Keeps Fluctuating

[Stefano Bianchi]

Thanks for your reply @haosdent.
I destroyed my VM and re build mesos 0.28 with just one master, and now is
working.
i will try to add another master but for the moment, since on openstack i
don't have much resources i need to use that VM as a slave.
However in the previous configuration the switch between two masters was
ok, just when the master was leading after, more or less 30 seconds, there
was that Failed to connect message.

Mesos interconnection among clusters project calico

[Stefano Bianchi]

Hi all

i have to set up two mesos clusters.
On each cluster i should integrate Project calico in order to distribute
tasks among the agents. But these tasks should be sent also from a slave of
one cluster to the slave of the other cluster.
I know that when i start calico on each slaves, it registers the hosts to
the ETCD_AUTHORITY so calico use etcd.
In order to have interconnection among 2 mesos clusters, i should have the
same etcd datastore for both my Mesos/Calico clusters.
Someone knows how to reach this condition?

Thanks in advance

Re: how to change mesos resources

[Stefano Bianchi]

YS haosdent!
that exactly works! And is exactly what i mean!!! Thank you a lot, thank
you all, and sorry if i asked you so many times.

Maybe is better if i present myself to you.

My name is Stefano Bianchi, Italian student of Telecommunication
engineering, i'm currently doing my master thesis at INFN European Nuclear
physics institute in Bologna city. I'm working on Tier 1 CNAF
infrastructure where the cloud infrastructure is based on an Openstack IaaS.
Here i have run 6 virtual machines 3 masters, for high availability, and 3
slaves, on one slave i'm running mesos DNS.
the final goal should be the implementation of a PaaS for science European
community which allows the exploitation of distributed datacenter resources
for some computations or experiments. For this purpose i have to integrate
projcect calico plugin in on mesos, in roder to distribute the tasks among
different network in a transparent way.

I'm describing my master thesis since i saw that many of you are Professors
and engineers, so you could have interest on that.

Thanks a lot, probbly in the next few months i will come to write here, for
the moment i really appreciate your help.
Thanks again!

Re: how to change mesos resources

[Stefano Bianchi]

i solved the chronos problem creating a hostname file in /etc/chronos
specifying the floating IP inside it.
Now all is working with changed resources, the only one problem that
persist is that after launching the command:

mesos-slave --master=131.154.96.32:5050 --hostname=131.154.96.52
--resources='cpu(*):1;mem(*):1300;disk(*):9000' --log_dir=/var/log/mesos

i still have some messages in command line and i cannot use the command
line.

You're right haosdent i want run mesos-slave as service, but to do that i
shoulf press ctrl+c to be able to use the command line, then i commonly
use: service mesos-slave start command, but running it i obtain that the
slave registers to the master allocating the default resources.
How can i fix the changes of resources and run mesos-slave with service
command?

Thanks again!

Re: how to change mesos resources

[Stefano Bianchi]

Im sorry, the command was just:

mesos-slave --master=131.154.xxx.xxx:5050 --hostname=131.154.xxx.xxx
--resources='cpu(*):1;mem(*):1000;disk(*):8000'

Where i specify the hostname with the floating IP.

Without
rm -f /tmp/mesos/meta/slaves/latest
Actually i dont know what this command means...even if i have run it before.

Re: how to change mesos resources

[Stefano Bianchi]

Sorry maybe i was not clear.
After that error with chronos i stopped the mesos slave and restarted it
witj service mesos-slave start, and in this way chronos job is working.
Of i stop the slavr and start it again with the command that changes the
resources i get the error.
In both cases i see in framework tab of mesos, that the hostname related to
chronos is non resolvable "mesos2.novalocal"
Im asking to my self if this can cause problem with this comamand:

rm -f /tmp/mesos/meta/slaves/latest

Sorry could not get your points here. What happens if you create a new
chronos job and launch it? Is it still error?

Re: how to change mesos resources

[Stefano Bianchi]

"I think maybe you clear your work_dir in agent. So those messages
disappear now. Does this always happen when you create a new chronos job?"

No it does not happen normally, that message comes out only after i
launched the command to change the reaources. Maybe i should create, as i
made both for mesos and marathon, the hostname file for Chronos in
/etc/chronos and put it inside the public IP resolvable ?

i checked in framework, and i see that in correspondence of chronos host

Re: how to change mesos resources

[Stefano Bianchi]

Thanks haosdent.
However i tried to see launch that command and what i see is:
1) Resources are increased, this is what i expected, good;
2) A Chronos Job that run each 2 minutes, is allocated and then "Staged";
is i click on sandbox i obtain this message:

Framework with ID 'c01b5040-6079-4f55-8ef2-089f0d4d1987-' does not
exist on slave with ID 'ad490064-1a6e-415c-8536-daef0d8e3572-S20'.

What does it means? How can i solve it?
However i tried to launch your command but i still unable to use the
terminal after that :P, this is another and minor issue.

Re: how to change mesos resources

[Stefano Bianchi]

Hi
All is working fine!
I can see more disk space and more RAM!
The only thing that is different is that with the Arjun last command, i
obtain a verbose output, i mean a lot of messages continuously shown, on
command line. i would like to hide them and continue to use the command
line, is it possible?

Thanks again!

Re: how to change mesos resources

[Stefano Bianchi]

i tried the command: free -m
and i obtained this output:
  totalusedfree  shared  buff/cache
  available

Mem:   1840 1201407  40 312
1507

Swap: 0   0   0

so there is not 2048 MB of RAM? i'm sure that openstack tells me that this
is a machine with 2048 MB of RAM...

Re: how to change mesos resources

[Stefano Bianchi]

What has to be clear is that i'm running virtual machines on openstack, so
i am not on bare metal.
All the VMs are Openstack Images, and each slave has been built with 2048
MB of RAM, so since slaves are 3 i should see in mesos something close to
6144 MB, but mesos shows only 2.7 GB.
If you look at the command output i posted in previous messages, the
current mesos resources configuration allows 920 MB and 5112 MB of disk
space for each slave. I would like that mesos can see for instance 2000 MB
of RAM and 9000 MB of disk. and for this reason i have run: mesos-slave
--master=MASTER_ADDRESS:5050 --resources='cpu:1;mem:2000;disk:9000'

June Taylor, i need to understand:
1) What the command you suggest do?
2) Should i stop mesos-slave before? and then run your command?

Thanks in advance.

how to change mesos resources

[Stefano Bianchi]

Hi i would like to enter in this mailing list.
i'm currently doing my Master Thesis on Mesos and Calico.
I'm working at INFN, institute of nuclear physics. The goal of the thesis
is to build a PaaS where mesos is the scheduler and Calico must allow the
interconnection between multiple datacenters linked to the CERN.

I'm exploiting an IaaS based on Openstack, here i have created 6 Virtual
Machines, 3 Masters and 3 Slaves, on one slave is running Mesos-DNS from
Marathon.
All is perfectly working, since i am on another network i changed correctly
the hostnames such that on mesos are resolvable and i tried to run from
marathon a simple http server which is scalable on all my machine. So all
is fine and working.

The only thing that i don't like is that each 3 slaves have 1 CPU 10 GB of
disk memory and 2GB of RAM, but mesos currently show for each one only 5 GB
of disk memory and 900MB of RAM.
So checking in documentation i found the command to manage the resources.
I stopped Slave1, for instance, and i have run this command:

mesos-slave --master=MASTER_ADDRESS:5050
--resources='cpu:1;mem:2000;disk:9000'

where i want set 2000 GB of RAM and 9000GB of disk memory.
 The output is the following:
