Exception at startup: failed to send ping request over multicast

Elastic Stack Elasticsearch

Hi,

I'm new here and I hope I'm in the right place.

I'm on Linux, Ubuntu 10.10. I have downloaded elasticsearch 0.13.1, and when I start it up with bin/elasticsearch -f this is what happens:

As you can see, an exception is raised about ping over multicast.
This also happens with versions 0.13.0 and 0.12.1, and also with the latest one compiled from source.

Of course nothing works then: when I try to XPUT anything, just like shown in the examples, what I get all the time is {"error":"MasterNotDiscoveredException[]"}
I guess this may be a problem of my configuration, but I don't know where to look at exactly, so help would be very much appreciated.

Do you have multicast enabled on your network? You can move to unicast
discovery.

2010/12/16 Shay Banon shay.banon@elasticsearch.com:

Do you have multicast enabled on your network?

Er, I'm not 100% sure about that (I'm deeply ignorant of this
subject), but I think it's enabled, since ifconfig reads:

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

for both eth0 and eth1; of course it is not enabled fot lo:

UP LOOPBACK RUNNING MTU:16436 Metric:1

so I still don't know what the problem with multicast may be.

You can move to unicast discovery.

I tried this by writing this into config/elasticsearch.yml

discovery.zen.ping.multicast:
enabled: false

With this, everything seems to work correctly (al least locally).
Thanks a lot! That probably does it for me.

You will still need to configure unicast discovery if you want it to work on
several machines. The address used to send the multicast requests on is the
publish address that you see in the log (for the transport for example).
Maybe the one guesses by ES to use is not the correct one?

The address used to send the multicast requests on is the
publish address that you see in the log (for the transport for example).
Maybe the one guessed by ES to use is not the correct one?

First off: please note that I'm just experimenting on my laptop, not a
server (yet), so my problems are probably outside the scope of ES and
it would be more than understandable on my part if you'd just ignore
them.

That said, in case you think it's worth trying to solve the issue,
here's the answer to your questions: the address guessed by ES is the
local network's 192.168.0.100, i.e. the same as that provided by
ifconfig for eth0.
I guess that the use of the local network might cause the issue with
multicast (but as I said I'm deeply ignorant of the subject). Perhaps
I should somehow force ES to use the public IP? Or modify my network's
configuration? (I tried opening the relevant ports and modifying my
router's configuration, with no luck.)

Log of ElasticSerach:

[2010-12-20 17:25:46,552][INFO ][transport ]
[Tarantula] bound_address {inet[/0:0:0:0:0:0:0:0:9300]},
publish_address {inet[/192.168.0.100:9300]}

Output of ifconfig:

inet addr:192.168.0.100 Bcast:192.168.0.255 Mask:255.255.255.0

thanks,

It seems like mcast should be enabled for eth0, so thats strange... . You
can try and change the network.publish_host to a different ip and see if it
helps?

server (yet), so my problems are probably outside the scope of ES and
it would be more than understandable on my part if you'd just ignore
them.

That said, in case you think it's worth trying to solve the issue,
here's the answer to your questions: the address guessed by ES is the
local network's 192.168.0.100, i.e. the same as that provided by
ifconfig for eth0.
I guess that the use of the local network might cause the issue with
multicast (but as I said I'm deeply ignorant of the subject). Perhaps
I should somehow force ES to use the public IP? Or modify my network's
configuration? (I tried opening the relevant ports and modifying my
router's configuration, with no luck.)

Do you have multicast enabled on your network?

Er, I'm not 100% sure about that (I'm deeply ignorant of this
subject), but I think it's enabled, since ifconfig reads:

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

for both eth0 and eth1; of course it is not enabled fot lo:

UP LOOPBACK RUNNING MTU:16436 Metric:1

so I still don't know what the problem with multicast may be.

You can move to unicast discovery.

I tried this by writing this into config/elasticsearch.yml

discovery.zen.ping.multicast:
enabled: false

With this, everything seems to work correctly (al least locally).
Thanks a lot! That probably does it for me.

I seem to have been successful by setting network.publish_host: 127.0.0.1 !!
At least, startup is smooth and everything seems to work just fine.

When I tried with my public IP instead it failed, like this:

[2010-12-20 19:56:43,476][INFO ][transport ] [Araña]

2010/12/20 Shay Banon shay.banon@elasticsearch.com:

It seems like mcast should be enabled for eth0, so thats strange... . You
can try and change the network.publish_host to a different ip and see if it
helps?
