Re: Initial leader election

[Guilherme Moro]

The nodes are quite fast to come up, but I will try to increase that for a
test anyway.
Either way, shouldn't the system try again automatically instead of just
issuing repeatedly "Replica in EMPTY status received a broadcasted recover
request" after a couple of failures?


Thanks for the answer.

why I have to set LIBPROCESS_IP for my framework?

[zhou weitao]

Hi, list:

as the subject. Whatever Marathon, chronos, Spark and so on, I have to set
the ENV LIBPROCESS_IP for registering them to mesos-master. But I doesn't
figure out why I have to do that yet. If possible, please shoot me some
info.

thanks in advance.

Re: why I have to set LIBPROCESS_IP for my framework?

[haosdent]

Hi, Mesos use libprocess, which need set LIBPROCESS_IP and LIBPROCESS_PORT
to communicate with.

Re: why I have to set LIBPROCESS_IP for my framework?

[Chengwei Yang]

Yes, both mesos-master/slave, scheduler use libprocess so far and you can set
LIBPROCESS_IP by set mesos-master/slave opton(--ip).

For scheduler which doesn't export an option to configure LIBPROCESS_IP then you
have to configure the environment yourself.

BUT only when your host not configured correclty.

`not configured correctly` means the local ip that libprocess got from hostname
is incorrect.

See code 3rdparty/libprocess/src/process.cpp:929-935, like below

```
$ sed -ne '929,935p' 3rdparty/libprocess/src/process.cpp
if (gethostname(hostname, sizeof(hostname)) < 0) {
  LOG(FATAL) << "Failed to initialize, gethostname: "
 << hstrerror(h_errno);
}

// Lookup IP address of local hostname.
Try ip = net::getIP(hostname, __address__.ip.family());
```

Ensure you have your host configured correctly. You may have to add a line to
`/etc/hosts` like

Hi weitao,

mesos use libprocess to communicate each other, that all.

Re: Anyone successfully setup CLION with mesos?

[Marco Massenzio]

I did set it up with CLion - it's not perfect (still a few "false
positives" on compile errors and it gets confused in places) but it's
definitely better than the best I was able to achieve with Eclipse (see my
blog link below for details on that one).

I can't exactly remember what I did to make it all work, but I think you
can just point it to the CMakeList.txt top-level file, then CLion will do
the rest and figure it out - Alex will correct me, but last time I tried, I
was only able to use it up to the `stouttests` target, I'm sure a lot more
work now.

At any rate, code navigation, auto-completion, etc. work just fine.
