Start Elastic Node without network link

[dadoonet]

When I try to launch an ES instance from scratch for test purpose without any network link up, it fails.

I have to connect at least one network card.

It would be nice if ES can start without a network (standalone mode) with the default parameters.

By the way, is there a network configuration to start ES without network signal ?

[kimchy]

What do you get when you set monitor.network to TRACE in the logging file?

[dadoonet]

Sure !

Cheers...

[dadoonet]

BTW, it only fails on my Linux (Ubuntu). On Windows, it starts perfectly with or without the Network link.
May be an OS issue ?
As it's a really small issue without importance (you never use ES without a Network, so spending time on it is not useful), I suggest to close the issue as a WontBeFix issue.

What do you think ?

[kimchy]

I think that it should be fixed for better OOB usage. I think it fails on the multicast discovery, we can warn then and still continue... . I need to get the full stack trace for the exception, can you check the log file itself (not the console output) with TRACE logging enabled? You should see the exception there...

[gsf]

I ran into the same issue. Log output with monitor.network set to TRACE:

This is from the log file, but looks quite a bit like dadoonet's paste above... should something else be set to TRACE as well?

[kimchy]

@gsf can you set bootstrap to DEBUG in the logging and check the log file for the full exception failure and paste it here?

[gsf]

Gotcha. The relevant stack trace is as follows:

[kimchy]

@gsf: cool, thanks!. Will push an enhancement so it will warn in this case that multicast discovery is disable, but still startup.

[dadoonet]

I'm coming too late to give the trace ! Shame on me :-(
Thanks @gsf to have provided it. Thanks @kimchy to close this issue.
