Re: Can not gather default cluster on localhost

Alexey,

Yes, I believe I am using the default config. I do not modify any fileof those came with Ignite nightly build, and I do not supply my own .xmlto `bin/ignite.sh` script, so I think I'm clean.

Could you please clarify, which exactly file to edit and how to set`TcpDiscoveryVmIpFinder` up with proper value? I am not a Java developerand not familiar with Ignite fine tuning.

Hello Dmitriy,

Did you use the default config shipped with Ignite? Can you try modifying
the config to use TcpDiscoveryVmIpFinder providing only 127.0.0.1:47500 in
the list of IP addresses?

Hello igniters!

I am again in need of your mighty helping hand.

Recently I experienced a strange bug. It may be a fresh regression, or
maybe I myself did something wrong. It would be great if someone looked
into this matter.

I have a need of testing some things in my client against a cluster of
multiple Ignite instances. If my understanding is correct, I can create
an Ignite cluster on localhost just by launching multiple
`bin/ignite.sh` in console(s) with no special parameters. I tried doing
so, but each Ignite instance I created was forming a separate cluster,
and no data sharing occurred.

I was told that in some cases IPv6 may prevent default Ignite instances
from gathering into a cluster, at least there was a same or similar case
with Ignite 2.7 on fresh MacOS X. I disabled IPv6 with

```
$ _JAVA_OPTIONS=-Djava.net.preferIPv4Stack=true bin/ignite.sh
```

but the outcome did not change. For me it looks like clustering is
enabled, but instances can not detect each other's presence.

My OS is Arch Linux. This is my java version:

```
$ java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
```

Output of the first console:
