slave_ping_timeout 1secs
Hi Running Mesos 0.23.0 and noted that cannot start mesos-master with slave_ping_timeout less than 1 second, tried 0.5secs, 500ms and 50us, etc. Is this by design or am I missing something?

I see. Thank you for the clarification. Can I just change the boundaries in the source code, to suit my needs, or there is more to it?

But running in on Mesos, it didn't work (permission denied)(Also thank you to MapR for helping me troubleshoot). Good news, there is a patch. https://issues.apache.org/jira/browse/MESOS-719 And it's fixed in Mesos 0.23. I applied the patch and recompiled and it worked great, and when I installed 0.23, it also worked great. Good luck.

Mesos and Docker Slave Problem
Hi
Running Mesos 0.22.1, on a setup with 2 docker slaves: One is running on kernel
3.13.0, with docker 1.6.2, and the other on kernel 3.14.5, with docker 1.7.1. I
am able to run Marathon tasks on the first one, e.g.,
{
id: hello -sleep,
cmd: while [ true ] ; do echo 'Hello Marathon' ; sleep 5 ; done,
cpus: 0.1,
mem: 10.0,
instances: 1,
}
However, trying to run the same task on the 2nd docker, leads to indefinite
wait in deployment. All I can gather, in terms of log, is the following on the
2nd slave:

I see. Nope, and pointing to the leading master shows the proper result☺ Thanks.
Is there a REST equivalent to mesos-resolve, so that one can ascertain who is
the leader without having to point to the leader?

Hi
Trying to get the list of active slaves, via cli, e.g. curl
http://10.4.50.80:5050/master/slaves | python -m json.tool and am not getting
the expected results. The returned value is empty:
{
slaves: []
}
, whereas, looking at web gui I can see that there are deployed slaves. Am I
missing something?
Cheers,

Mesos Slave Failover time
Hi
Trying to adjust the current failover time to below 10 seconds and don't seem
to be able to find the right set of parameters. Currently, it takes around
minute and half for master to detect that a slave has gone offline, which seems
to correspond to slave_ping_timeout=15*max_slave_ping_timeouts=5. However, I
can't find these parameters in mesos-master:
# mesos-master --version
mesos 0.22.1
#mesos-master --help
Usage: mesos-master [...]
Supported options:
--acls=VALUE The value could be a JSON formatted
string of ACLs
or a file path containing the JSON
formatted ACLs used
for authorization. Path could be of
the form 'file:///path/to/file'
or '/path/to/file'.
See the ACLs protobuf in mesos.proto
for the expected format.
Example:
{
register_frameworks: [
{
principals: { type: ANY },
roles: {
values: [a] }
}
],
run_tasks: [
{
principals: {
values: [a, b] },
users: {
values: [c] }
}
],
shutdown_frameworks: [
{
principals: {
values: [a, b] },
framework_principals: { values: [c] }
}
]
}
--allocation_interval=VALUE Amount of time to wait between
performing
(batch) allocations (e.g., 500ms,
1sec, etc). (default: 1secs)
--[no-]authenticate If authenticate is 'true' only
authenticated frameworks are allowed
to register. If 'false'
unauthenticated frameworks are also
allowed to register. (default: false)
--[no-]authenticate_slaves If 'true' only authenticated slaves
are allowed to register.
If 'false' unauthenticated slaves
are also allowed to register. (default: false)
--authenticators=VALUE Authenticator implementation to use
when authenticating frameworks
and/or slaves. Use the default
'crammd5', or
load an alternate authenticator
module using --modules. (default: crammd5)
--cluster=VALUE Human readable name for the cluster,
displayed in the webui.
--credentials=VALUE Either a path to a text file with a
list of credentials,
each line containing 'principal' and
'secret' separated by whitespace,
or, a path to a JSON-formatted file
containing credentials.
Path could be of the form
'file:///path/to/file' or '/path/to/file'.
JSON file Example:
{
credentials: [
{
principal:
sherman,
secret:
kitesurf,
}
]
}
Text file Example:
username secret
--external_log_file=VALUESpecified the externally managed log
file. This file will be
exposed in the webui and HTTP api.
This is useful when using
