Re: mesos-slave Failed to initialize: Failed to bind on 0.0.0.0:0: Address already in use: Address already in use [98]

fwiw, I've seen this type of error in the past when the system runs out of
ephemeral ports. Not saying this definitely the same issue, but I suggest
checking to see if you have ephemeral ports available.

Mesos slave ID change after reboot

2018-01-10 Thread Srikanth Viswanathan
I am trying to understand under what cases the mesos slave ID changes in
response to reboot.  I noticed this note at
http://mesos.apache.org/documentation/latest/upgrades/#upgrading-from-1-3-x-to-1-4-x
:

Agent is now allowed to recover its agent ID post a host reboot. This
> prevents the unnecessary discarding of agent ID by prior Mesos versions.
> Notes about backwards compatibility:
>
>- In case the agent’s recovery runs into agent info mismatch which may
>happen due to resource change associated with reboot, it’ll fall back to
>recovering as a new agent (existing behavior).
>
>
>- In other cases such as checkpointed resources (e.g. persistent
>volumes) being incompatible with the agent’s resources the recovery will
>still fail (existing behavior).
>

I was wondering if the behavior prior to 1.3 is also similarly
well-defined. Is the answer "Will always change after a reboot"?

Thanks,
Srikanth


MesosCon Hackathon agenda

2017-07-25 Thread Srikanth Viswanathan
Hi folks,

Are there any details on what the MesosCon North America 2017 hackathon
will be about? Trying to decide whether to register for the hackathon.


In the past, there have been hackathon's with very specific agendas, as
well as more open hackathons that allow beginner contributions to mesos.


Thanks,

Dynamic reservations without a principal

2017-07-04 Thread Srikanth Viswanathan
Hi folks,

I am trying to have the Chronos framework consume dynamic reservations in
Mesos. However, it appears that Chronos is unable to do this because it
does not pass the framework principal to Mesos when launching tasks (See
https://github.com/mesos/chronos/issues/843), which makes Mesos reject the
launch operation.

To get around this, I am considering changing my dynamic reservations to be
purely role-based instead of (role, principal)-based. Is this
allowed/valid? http://mesos.readthedocs.io/en/0.24.1/reservation/#
dynamic-reservation-since-0230 says "resources are reserved for a *role*." Does
this mean I can make a dynamic reservation just for (role) instead of
(role, principal)?

Thanks,
Srikanth


Re: "Chaos monkey" for mesos?

Sorry, ignore my first question. A framework can obviously kill tasks. I
was just unsure as to whether it can kill foreign tasks, which leaves only
my second question.

Re: "Chaos monkey" for mesos?

2016-02-25 Thread Srikanth Viswanathan
Appreciate all the responses here. I'll look into `mesos-execute`.

I was thinking about the framework idea in passing but my mesos knowledge
isn't up to scratch yet, so I haven't been able pursue it yet. There are
many questions in my mind w.r.t designing this as a framework:
* Doesn't a framework only receive offers from mesos and launch tasks? How
would a framework kill tasks? Can it also kill slaves?
* Is it legal in mesos for one framework to kill tasks belonging to another
framework?

Thanks.

Thanks. Craig and David. I'm curious about the design and use of that tool.
Based on the video, it looks close to what I hope to do.

A web search didn't yield any results about it, however. Does anyone here
know more about the dcos chaos tool?

Thanks again.

"Chaos monkey" for mesos?

2016-02-25 Thread Srikanth Viswanathan
Has there been any work done to develop a "chaos monkey
" analogue for
Mesos? I have been researching on how to write one, but I wanted to know if
there's any work already available that I can take a look at for
comparison, and possibly re-use.

The end goal would be something loaded into Mesos or separate from Mesos
that randomly kills tasks. Could it be something as simple as an
application that uses the KILL HTTP request from the scheduler API to kill
tasks?

Thanks.
