javanna 27d4994aff Merge branch 'master' into enhancement/remove_node_client_setting 2016-03-24 18:10:11 +01:00
Boaz Leskes 6dd164d0bd Include pings from client nodes in master election
We currently have a `discovery.zen.master_election.filter_client` setting that control whether their ping responses are ignored for master election (which is the current default). With the push to treat client nodes as normal nodes (and promote the transport/rest clients for client work), this should be changed. This commit remove this setting and it's companion `discovery.zen.master_election.filter_data` setting (currently defaulting to  false) in favor of singe `discovery.zen.master_election.ignore_non_master_pings` setting with more intuitive name (defaulting to false).

Resolves #17325
Closes #17329

David Pilato f230eabc15 [cloud-azure] Split azure plugin in 3 plugins
Until now we had a cloud-azure plugin which is providing 3 distinct features:

* discovery on Azure
* snapshot/restore on Aure
* SMB store

This commit splits the plugin by feature so people can use either one or the other or both features.

Doc is updated accordingly.

Ryan Ernst 164efaecbe Networking: Move multicast discovery to a plugin
Multicast has known issues (see #12999 and #12993). This change moves
multicast into a plugin, and deprecates it in the docs.  It also allows
for plugging in multiple zen ping implementations.

    Handle node mode across entire test cluster

    We used static methods reading sys properties to define the node mode
    per cluster. this had lots of problems when tests couldn't cope with
    mixed or only local mode. Now we are passing it down to the cluster from the test
    which allows to @SuppressNetworkMode / @SupressLocalMode on the test to force
    consistent node configurations.

    Default to unicast discovery, with default host list of 127.0.0.1, [::1]
2015-08-20 14:26:40 -04:00
Robert Muir 68307aa9f3 Fix network binding for ipv4/ipv6
When elasticsearch is configured by interface (or default: loopback interfaces),
bind to all addresses on the interface rather than an arbitrary one.

If the publish address is not specified, default it from the bound addresses
based on the following sort ordering:

* ipv4/ipv6 (java.net.preferIPv4Stack, defaults to true)
* ordinary addresses
* site-local addresses
* link local addresses
* loopback addresses

One one address is published, and multicast is still always over ipv4: these
need to be future improvements.

Boaz Leskes 1e35bf3171 Discovery: wait on incoming joins before electing local node as master
During master election each node pings in order to discover other nodes and validate the liveness of existing nodes. Based on this information the node either discovers an existing master or, if enough nodes are found (based on `discovery.zen.minimum_master_nodes>>) a new master will be elected.

Currently, the node that is elected as master will currently update it the cluster state to indicate the result of the election. Other nodes will submit a join request to the newly elected master node. Instead of immediately processing the election result, the elected master
node should wait for the incoming joins from other nodes, thus validating the elections result is properly applied. As soon as enough nodes have sent their joins request (based on the `minimum_master_nodes` settings) the cluster state is modified.

Note that if `minimum_master_nodes` is not set, this change has no effect.

Shay Banon 2330421816 Wait till node is part of cluster state for join process
When a node sends a join request to the master, only send back the response after it has been added to the master cluster state and published.
This will fix the rare cases where today, a join request can return, and the master, since its under load, have not yet added the node to its cluster state, and the node that joined will start a fault detect against the master, failing since its not part of the cluster state.
Since now the join request is longer, also increase the join request timeout default.

Introduce a dedicated join.timeout setting, that by default is 10x the ping.timeout (so 30s by default).
