Thread pool settings are no longer dynamically updatable since
da74323141. This commit removes a leftover
note from the thread pool module docs that incorrectly states that
thread pool settings are dynamically updatable.
This commit refactors the handling of thread pool settings so that the
individual settings can be registered rather than registering the top
level group. With this refactoring, individual plugins must now register
their own settings for custom thread pools that they need, but a
dedicated API is provided for this in the thread pool module. This
commit also renames the prefix on the thread pool settings from
"threadpool" to "thread_pool". This enables a hard break on the settings
so that:
- some of the settings can be given more sensible names (e.g., the max
number of threads in a scaling thread pool is now named "max" instead
of "size")
- change the soft limit on the number of threads in the bulk and
indexing thread pools to a hard limit
- the settings names for custom plugins for thread pools can be
prefixed (e.g., "xpack.watcher.thread_pool.size")
- remove dynamic thread pool settings

This commit removes the ability to specify a custom plugins
path. Instead, the plugins path will always be a subdirectory called
"plugins" off of the home directory.
The syntax highlighter only supports [source,js].
Also adds a check to the rest test generator that runs during
the build that'll fail the build if it sees `[source,json]`.
Today when parsing settings during bootstrap, we add a system property
for every Elasticsearch setting. Additionally, settings can be set via
system properties. This commit simplifies this situation.
- settings are no longer propogated to system properties
- system properties can not be used to set settings
- the "es." prefix on settings is no longer required (nor permitted)
- test logging has a dedicated system property (tests.logger.level)

This removes all the mentions of the sandbox from the script engine
services and permissions model. This means that the following settings
are no longer supported:
```yaml
script.inline: sandbox
script.stored: sandbox
```
Instead, only a `true` or `false` value can be specified.
Since this would otherwise break the default-allow parameter for
languages like expressions, painless, and mustache, all script engines
have been updated to have individual settings, for instance:
```yaml
script.engine.groovy.inline: true
```
Would enable all inline scripts for groovy. (they can still be
overridden on a per-operation basis).
Expressions, Painless, and Mustache all default to `true` for inline,
file, and stored scripts to preserve the old scripting behavior.
Resolves#17114
Remove performance hack for accessing a document's fields, its not needed.
Add support for accessing is-getter methods like List.isEmpty() as .empty
Closes#18201
This gives better coverage and consistency with the scripting APIs, by
whitelisting the primary search scripting API classes and using them instead
of only Map and List methods.
For example, accessing fields can now be done with `.value` instead of `.0`
because `getValue()` is whitelisted. For now, access to a document's fields in
this way (loads) are fast-pathed in the code, to avoid dynamic overhead.
Access to geo fields and geo distance functions is now supported.

Adds infrastructure so `gradle :docs:check` will extract tests from
snippets in the documentation and execute the tests. This is included
in `gradle check` so it should happen on CI and during a normal build.
By default each `// AUTOSENSE` snippet creates a unique REST test. These
tests are executed in a random order and the cluster is wiped between
each one. If multiple snippets chain together into a test you can annotate
all snippets after the first with `// TEST[continued]` to have the
generated tests for both snippets joined.
Snippets marked as `// TESTRESPONSE` are checked against the response
of the last action.
See docs/README.asciidoc for lots more.

With this commit we compress HTTP responses provided the client
supports it (as indicated by the HTTP header 'Accept-Encoding').
We're also able to process compressed HTTP requests if needed.
The default compression level is lowered from 6 to 3 as benchmarks
have indicated that this reduces query latency with a negligible
increase in network traffic.
Closes#7309
This commit actually bounds the size of the generic thread pool. The
generic thread pool was of type cached, a thread pool with an unbounded
number of workers and an unbounded work queue. With this commit, the
generic thread pool is now of type scaling. As such, the cached thread
pool type has been removed. By default, the generic thread pool is
constructed with a core pool size of four, a max pool size of 128 and
idle workers can be reaped after a keep-alive time of thirty seconds
expires. The work queue for this thread pool remains unbounded.
With this commit we limit the size of all in-flight requests on
transport level. The size is guarded by a circuit breaker and is
based on the content size of each request.
By default we use 100% of available heap meaning that the parent
circuit breaker will limit the maximum available size. This value
can be changed by adjusting the setting
network.breaker.inflight_requests.limit

This commit adds a new configuration file jvm.options to centralize and
simplify management of JVM options. This separates the configuration of
the JVM from the packaging scripts (bin/elasticsearch*, bin/service.bat,
and init.d/elasticsearch) simplifying end-user operational management of
custom JVM options.
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#17325Closes#17329
In #17198, we removed suggest transport action, which
used the `suggest` threadpool to execute requests. Now
`suggest` threadpool is unused and suggest requests are
executed on the `search` threadpool.
Today, certain bootstrap properties are set and read via system
properties. This action-at-distance way of managing these properties is
rather confusing, and completely unnecessary. But another problem exists
with setting these as system properties. Namely, these system properties
are interpreted as Elasticsearch settings, not all of which are
registered. This leads to Elasticsearch failing to startup if any of
these special properties are set. Instead, these properties should be
kept as local as possible, and passed around as method parameters where
needed. This eliminates the action-at-distance way of handling these
properties, and eliminates the need to register these non-setting
properties. This commit does exactly that.
Additionally, today we use the "-D" command line flag to set the
properties, but this is confusing because "-D" is a special flag to the
JVM for setting system properties. This creates confusion because some
"-D" properties should be passed via arguments to the JVM (so via
ES_JAVA_OPTS), and some should be passed as arguments to
Elasticsearch. This commit changes the "-D" flag for Elasticsearch
settings to "-E".
Currently we suggesting users create a Node (using NodeBuilder in 2.x) to have a client that is capable of keeping up-to-date information. This is generally a bad idea as it means elasticsearch has no control over eg max heap size or gc settings, and is also problematic for users because they must deal with dependency collisions (and in 2.x+ dependencies of elasticsearch itself).
A better alternative, and what we should document, is to run a local elasticsearch server using bin/elasticsearch, and then use the transport client to connect to that local node. This local connection is virtually free, and allows the client code to be completely isolated from the elasticsearch process. Plugins are then also easy to deal with: just install them in elasticsearch as usual.

2.x has show so far that running with security manager is the way to go.
This commit make this non-optional. Users that need to pass their own rules
can still do this via the system configuration for the security manager. They
can even opt out of all security that way.
This setting was missing from the docs, so I added it. However, I also
completely rewrote the nodes documentation page because it was mostly
talking about client nodes with some issues, without ever discussing
master nodes, or even tribe nodes. All nodes should be listed on a
"nodes" documentation page.
Fixes#15903Fixed#14429
Today we throttle recoveries only for incoming recoveries. Nodes that have a lot
of primaries can get overloaded due to too many recoveries. To still keep that at bay
we limit the number of threads that are sending files to the target to overcome this problem.
The right solution here is to also throttle the outgoing recoveries that are today unbounded on
the master and don't start the recovery until we have enough resources on both source and target nodes.
The concurrency aspects of the recovery source also added a lot of complexity and additional threadpools
that are hard to configure. This commit removes the concurrent streamns notion completely and sends files
in the thread that drives the recovery simplifying the recovery code considerably.
Outgoing recoveries are not throttled on the master via a allocation decider.
This makes some minor improvements (does not fix all problems!)
It reorders unicast disco in elasticsearch.yml to be right after the network host,
for better locality.
It removes the warning (unreleased) about publish addresses, lets try to really discourage setting
that unless you need to (behind a proxy server). Most people should be fine with `network.host`
Finally it reorganizes the network docs page a bit:
We add a table of 4 "basic" settings at the very beginning:
* network.host
* discovery.zen.ping.unicast.hosts
* http.port
* transport.tcp.port
The first two being the most important, which addresses to bind and talk to, and the other two
being the port numbers.
The rest of the stuff I tried to simplify and reorder under "advanced" headers.
This is just a quick stab, I still think we need more effort into this thing, but we gotta start somewhere.
This commit forbids the changing of thread pool types for any thread
pool. The motivation here is that these are expert settings with
little practical advantage.

When running in GCE platform, an instance has access to:
http://metadata.google.internal/computeMetadata/v1/instance/network-interfaces/0/ip
Which gives back the private IP address, for example `10.240.0.2`.
http://metadata.google.internal/computeMetadata/v1/instance/network-interfaces/0/externalIp
Gives back the public Ip address, for example `130.211.108.21`.
As we have for `ec2`, we can support new network host settings:
* `_gce:privateIp:X_`: The private IP address of the machine for a given network interface.
* `_gce:hostname_`: The hostname of the machine.
* `_gce_`: Same as `_gce:privateIp:0_` (recommended).
Closes#13605.
Closes#13590.
BTW resolveIfPossible now throws IOException so code is also updated for ec2 discovery and
some basic tests have been added.
With 2.0, we now bind to `localhost` by default instead of binding to the network card and use its IP address.
When the discovery plugin gets from AWS API the list of nodes that should form the cluster, this list is pinged then. But as each node is bound to `localhost`, ping does not get an answer and the node elects itself as the master node.
`network.host` must be set.
Closes#13589.
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.
Until now we had a cloud-aws plugin which is providing 2 disctinct features:
* discovery on EC2
* snapshot/restore on S3
This commit splits the plugin by feature so people can use either one or the other or both features.
Doc is updated accordingly.
Prior to 2.0 we summed up the available space on all disk on a node
due to the raid-0 like behavior. Now we don't do this anymore and use the
min & max disk space to make decisions.

Default to unicast discovery, with default host list of 127.0.0.1, [::1]
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.

This commit updates the Zen Discovery documentation to explain which
nodes partcipate in master election (by default) as well as the
configuration parameters for controlling this.
Closes#12727
Today this is "unofficial" as conf/scripts, but some people
want to share scripts across different nodes and so on. Because
they cannot configure it, they are forced to use dirty hacks
like symbolic links, which isnt going to work: we aren't going
to recursively scan conf/ and add permissions to all link targets
underneath it, thats crazy.
I really hate adding yet another configuration knob here, but
users resorting to using symlinks are going to be frustrated,
and do things in a more insecure way.
The release and smoke test python scripts used to install
plugins in the old fashion.
Also the BATS testing suite installed/removed plugins in that
way. Here the marvel tests have been removed, as marvel currently
does not work with the master branch.
In addition documentation has been updated as well, where it was
still missing.
In order to unify the handling and reuse the CLITool infrastructure
the plugin manager should make use of this as well.
This obsolets the -i and --install options but requires the user
to use `install` as the first argument of the CLI.
This is basically just a port of the existing functionality, which
is also the reason why this is not a refactoring of the plugin manager,
which will come in a separate commit.
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.
Closes#12161
Require urls for URL repository to be listed in repositories.url.allowed_urls setting. This change ensures that only authorized URLs can be accessed by elasticsearch
Plugin Manager can now use another simplified form when a user wants to install an official plugin hosted at elasticsearch download service.
The form we use is:
```sh
bin/plugin install pluginname
```
As plugins share now the same version as elasticsearch, we can automatically guess what is the exact current version of the plugin manager script.
Also, download service will now use `/org.elasticsearch.plugins/pluginName/pluginName-version.zip` URL path to download a plugin.
If the older form is provided (`user/plugin/version` or `user/plugin`), we will still use:
* elasticsearch download service at `/user/plugin/plugin-version.zip`
* maven central with groupIp=user, artifactId=plugin and version=version
* github with user=user, repoName=plugin and tag=version
* github with user=user, repoName=plugin and branch=master if no version is set
Note that community plugin providers can use other download services by using `--url` option.
If you try to use the new form with a non core elasticsearch plugin, the plugin manager will reject
it and will give you all known core plugins.
```
Usage:
-u, --url [plugin location] : Set exact URL to download the plugin from
-i, --install [plugin name] : Downloads and installs listed plugins [*]
-t, --timeout [duration] : Timeout setting: 30s, 1m, 1h... (infinite by default)
-r, --remove [plugin name] : Removes listed plugins
-l, --list : List installed plugins
-v, --verbose : Prints verbose messages
-s, --silent : Run in silent mode
-h, --help : Prints this help message
[*] Plugin name could be:
elasticsearch-plugin-name for Elasticsearch 2.0 Core plugin (download from download.elastic.co)
elasticsearch/plugin/version for elasticsearch commercial plugins (download from download.elastic.co)
groupId/artifactId/version for community plugins (download from maven central or oss sonatype)
username/repository for site plugins (download from github master)
Elasticsearch Core plugins:
- elasticsearch-analysis-icu
- elasticsearch-analysis-kuromoji
- elasticsearch-analysis-phonetic

In order to be more consistent with what they do, the query cache has been
renamed to request cache and the filter cache has been renamed to query
cache.
A known issue is that package/logger names do no longer match settings names,
please speak up if you think this is an issue.
Here are the settings for which I kept backward compatibility. Note that they
are a bit different from what was discussed on #11569 but putting `cache` before
the name of what is cached has the benefit of making these settings consistent
with the fielddata cache whose size is configured by
`indices.fielddata.cache.size`:
* index.cache.query.enable -> index.requests.cache.enable
* indices.cache.query.size -> indices.requests.cache.size
* indices.cache.filter.size -> indices.queries.cache.size
Close#11569
Today, we disable CORS by default, but if a user simply enables CORS their instance of
elasticsearch will allow cross origin requests from anywhere, as the default value for allowed
origins is `*`.
This changes the default to be `null` so that no origins are allowed and the user must explicitly
specify the origins they wish to allow requests from. The documentation also mentions that there
is a security risk in using `*` as the value.
Closes#11169
Information about in-progress snapshot and restore processes is not really metadata and should be represented as a part of the cluster state similar to discovery nodes, routing table, and cluster blocks. Since in-progress snapshot and restore information is no longer part of metadata, this refactoring also enables us to handle cluster blocks in more consistent manner and allow creation of snapshots of a read-only cluster.
Closes#8102
While we had initially planned to keep rivers around in 2.0 to ease migration,
keeping support for rivers is challenging as it conflicts with other important
changes that we want to bring to 2.0 like synchronous dynamic mappings updates.
Nothing impossible to fix, but it would increase the complexity of how we
deal with dynamic mappings updates and manage rivers, while handling dynamic
mappings updates correctly is important for resiliency and rivers are on the go.
So removing rivers in 2.0 may well be a better trade-off.
The ResourceWatcher used settings prefixed `watcher.`, which
potentially could clash with the watcher plugin.
In order to prevent confusion, the settings have been renamed to
`resource.reload` prefixes.
This also uses the deprecation logging infrastructure introduced
in #11033 to log deprecated settings and their alternative at
startup.
Closes#11175
This change unifies the way scripts and templates are specified for all instances in the codebase. It builds on the Script class added previously and adds request building and parsing support as well as the ability to transfer script objects between nodes. It also adds a Template class which aims to provide the same functionality for template APIs
Closes#11091
Added infrastructure to allow basic member methods in the expressions
language to be called. The methods must have a signature with no arguments. Also
added the following member methods for date fields (and it should be easy to add more)
* getYear
* getMonth
* getDayOfMonth
* getHourOfDay
* getMinutes
* getSeconds
Allow fields to be accessed without using the member variable [value].
(Note that both ways can be used to access fields for back-compat.)

Groovy sandboxing was disabled by default from 1.4.3 on though since we found out that it could be worked around, so it makes little sense to keep it and maintain it.
Closes#10156Closes#10480
* Removed the docs for `index.compound_format` and `index.compound_on_flush` - these are expert settings which should probably be removed (see https://github.com/elastic/elasticsearch/issues/10778)
* Removed the docs for `index.index_concurrency` - another expert setting
* Labelled the segments verbose output as experimental
* Marked the `compression`, `precision_threshold` and `rehash` options as experimental in the cardinality and percentile aggs
* Improved the experimental text on `significant_terms`, `execution_hint` in the terms agg, and `terminate_after` param on count and search
* Removed the experimental flag on the `geobounds` agg
* Marked the settings in the `merge` and `store` modules as experimental, rather than the modules themselves
Closes#10782
* In code, we mark `River`, `AbstractRiverComponent`, `RiverComponent` and `RiverName` classes as deprecated
* We log that information when a cluster is still using it
* We add this information in the plugins list as well
Plugins can now define multiple operations/contexts that they use scripts for. Fine-grained settings can then be used to enable/disable scripts based on each single registered context.
Also added a new generic category called `plugin`, which will be used as a default when the context is not specified. This allows us to restore backwards compatibility for plugins on `ScriptService` by restoring the old methods that don't require the script context and making them internally use the `plugin` context, as they can only be called from plugins.
Closes#10347Closes#10419
Now that fine-grained script settings are supported (#10116) we can remove support for the script.disable_dynamic setting.
Same result as `script.disable_dynamic: false` can be obtained as follows:
```
script.inline: on
script.indexed: on
```
An exception is thrown at startup when the old setting is set, so we make sure we tell users they have to change it rather than ignoring the setting.
Closes#10286
Allow to on/off scripting based on their source (where they get loaded from), the operation that executes them and their language.
The settings cover the following combinations:
- mode: on, off, sandbox
- source: indexed, dynamic, file
- engine: groovy, expressions, mustache, etc
- operation: update, search, aggs, mapping
The following settings are supported for every engine:
script.engine.groovy.indexed.update: sandbox/on/off
script.engine.groovy.indexed.search: sandbox/on/off
script.engine.groovy.indexed.aggs: sandbox/on/off
script.engine.groovy.indexed.mapping: sandbox/on/off
script.engine.groovy.dynamic.update: sandbox/on/off
script.engine.groovy.dynamic.search: sandbox/on/off
script.engine.groovy.dynamic.aggs: sandbox/on/off
script.engine.groovy.dynamic.mapping: sandbox/on/off
script.engine.groovy.file.update: sandbox/on/off
script.engine.groovy.file.search: sandbox/on/off
script.engine.groovy.file.aggs: sandbox/on/off
script.engine.groovy.file.mapping: sandbox/on/off
For ease of use, the following more generic settings are supported too:
script.indexed: sandbox/on/off
script.dynamic: sandbox/on/off
script.file: sandbox/on/off
script.update: sandbox/on/off
script.search: sandbox/on/off
script.aggs: sandbox/on/off
script.mapping: sandbox/on/off
These will be used to calculate the more specific settings, using the stricter setting of each combination. Operation based settings have precedence over conflicting source based ones.
Note that the `mustache` engine is affected by generic settings applied to any language, while native scripts aren't as they are static by definition.
Also, the previous `script.disable_dynamic` setting can now be deprecated.

Adds a setting to disable detailed error messages and full exception stack traces
in HTTP responses. When set to false, the error_trace request parameter will result
in a HTTP 400 response. When the error_trace parameter is not present, the message
of the first ElasticsearchException will be output and no nested exception messages
will be output.
The request tracer logs in TRACE level under the `transport.tracer` log and is dynamically configurable with include and exclude arrays to filter out unneeded info. By default all requests are logged with the exception of fault detection pings (fired every second).
add the notion of tracers in the MockTransportService for testing purposes
Closes#9286
Together with #8782 it should help in the situations simliar to #8887 by adding an ability to get information about currently running snapshot without accessing the repository itself.
Closes#8887
We only have a single gatweway since es 1.3. There is no need to keep all
these abstractsion and nested packages. We can fold most of it into simpler
structures.
This change adds a 'http.publish_port' setting to the HTTP module to configure
the port which HTTP clients should use when communicating with the node. This
is useful when running on a bridged network interface or when running behind
a proxy or firewall.
Closes#8807Closes#8137
Always use the LocalGateway* equivalents
We already check in the LocalGateway whether a node is a client node, or
is not master-eligible, and skip writing the state there. This allows us
to remove this code that was previously used only for tribe nodes (which
are not master eligible anyway and wouldn't write state) and in
tests (which can shake more bugs out)
This adds HTTP pipelining support to netty. Previously pipelining was not
supported due to the asynchronous nature of elasticsearch. The first request
that was returned by Elasticsearch, was returned as first response,
regardless of the correct order.
The solution to this problem is to add a handler to the netty pipeline
that maintains an ordered list and thus orders the responses before
returning them to the client. This means, we will always have some state
on the server side and also requires some memory in order to keep the
responses there.
Pipelining is enabled by default, but can be configured by setting the
http.pipelining property to true|false. In addition the maximum size of
the event queue can be configured.
The initial netty handler is copied from this repo
https://github.com/typesafehub/netty-http-pipeliningCloses#2665
This commit adds the ability to enable / disable relocations
on an entire cluster or on individual indices for either:
* `primaries` - only primaries can rebalance
* `replica` - only replicas can rebalance
* `all` - everything can rebalance (default)
* `none` - all rebalances are disabled
similar to the allocation enable / disable functionality.
Relates to #7288
This patch allows to create several netty bootstrap, each of which
listening on different ports. This will potentially allow for features
to listen to different network interfaces for node-to-node or node-to-client
communication and is also the base to listen to several interfaces, so that those
can be used to speed up cluster communication in the future.
Closes#8098
Today, when executing an action (mainly when using the Java API), a listener threaded flag can be set to true in order to execute the listener on a different thread pool. Today, this thread pool is the generic thread pool, which is cached. This can create problems for Java clients (mainly) around potential thread explosion.
Introduce a new thread pool called listener, that is fixed sized and defaults to the half the cores maxed at 10, and use it where listeners are executed.

BlobContainer used to provide async APIs which are not used
internally. The implementation of these APIs are also not async
by nature and neither is any of the pluggable BlobContainers. This
commit simplifies the API to a simple input / output stream and
reduces the hierarchy of BlobContainer dramatically.
NOTE: This is a breaking change!

The `recovery_after_time` tells the gateway to wait before starting recovery from disk. The goal here is to allow for more nodes to join the cluster and thus not start potentially unneeded replications. The `expectedNodes` setting (and friends) tells the gateway when it can start recovering even if the `recover_after_time` has not yet elapsed. However, `expectedNodes` is useless if one doesn't set `recovery_after_time`. This commit changes that by setting a sensible default of 5m for `recover_after_time` *if* a `expectedNodes` setting is present.
Closes#6742
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.
closes#6480
Using ping.timeout, which defaults to 3s, to use as a timeout value on the join request a node makes to the master once its discovered can be too small, specifically when there is a large cluster state involved (and by definition, all the buffers and such on the nio layer will be "cold"). Introduce a dedicated join.timeout setting, that by default is 10x the ping.timeout (so 30s by default).
closes#6342
This change adds a new cluster state that waits for the replication of a shard to finish before starting snapshotting process. Because this change adds a new snapshot state, an pre-1.2.0 nodes will not be able to join the 1.2.0 cluster that is currently running snapshot/restore operation.
Closes#5531
* If plugin does not provide `lucene` property, we consider that the plugin is compatible.
* If plugin provides `lucene` property, we try to load related Enum org.apache.lucene.util.Version. If this fails, it means that the node is too "old" comparing to the Lucene version the plugin was built for.
* We compare then two first digits of current node lucene version against two first digits of plugin Lucene version. If not equal, it means that the plugin is too "old" for the current node.
Plugin developers who wants to launch plugin check only have to add a `lucene` property in `es-plugin.properties` file. If you are using maven to build your plugin, you can do it like this:
In `pom.xml`:
```xml
<properties>
<lucene.version>4.6.0</lucene.version>
</properties>
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
</build>
```
In `es-plugin.properties`, add:
```properties
lucene=${lucene.version}
```
BTW, if you don't already have it, you can add the plugin version as well:
```properties
version=${project.version}
```
You can disable that check using `plugins.check_lucene: false`.
The current setting of 20MB/sec seems to be too conservative given
the capabilities of modern hardware / network throughput.
A 50MB default should provide better out of the box performance.
