This adds a new `/_cluster/allocation/explain` API that explains why a
shard can or cannot be allocated to nodes in the cluster. Additionally,
it will show where the master *desires* to put the shard, according to
the `ShardsAllocator`.
It looks like this:
```
GET /_cluster/allocation/explain?pretty
{
"index": "only-foo",
"shard": 0,
"primary": false
}
```
Though, you can optionally send an empty body, which means "explain the
allocation for the first unassigned shard you find".
The output when a shard is unassigned looks like this:
```
{
"shard" : {
"index" : "only-foo",
"index_uuid" : "KnW0-zELRs6PK84l0r38ZA",
"id" : 0,
"primary" : false
},
"assigned" : false,
"unassigned_info" : {
"reason" : "INDEX_CREATED",
"at" : "2016-03-22T20:04:23.620Z"
},
"nodes" : {
"V-Spi0AyRZ6ZvKbaI3691w" : {
"node_name" : "Susan Storm",
"node_attributes" : {
"bar" : "baz"
},
"final_decision" : "NO",
"weight" : 0.06666675,
"decisions" : [ {
"decider" : "filter",
"decision" : "NO",
"explanation" : "node does not match index include filters [foo:\"bar\"]"
} ]
},
"Qc6VL8c5RWaw1qXZ0Rg57g" : {
"node_name" : "Slipstream",
"node_attributes" : {
"bar" : "baz",
"foo" : "bar"
},
"final_decision" : "NO",
"weight" : -1.3833332,
"decisions" : [ {
"decider" : "same_shard",
"decision" : "NO",
"explanation" : "the shard cannot be allocated on the same node id [Qc6VL8c5RWaw1qXZ0Rg57g] on which it already exists"
} ]
},
"PzdyMZGXQdGhqTJHF_hGgA" : {
"node_name" : "The Symbiote",
"node_attributes" : { },
"final_decision" : "NO",
"weight" : 2.3166666,
"decisions" : [ {
"decider" : "filter",
"decision" : "NO",
"explanation" : "node does not match index include filters [foo:\"bar\"]"
} ]
}
}
}
```
And when the shard *is* assigned, the output looks like:
```
{
"shard" : {
"index" : "only-foo",
"index_uuid" : "KnW0-zELRs6PK84l0r38ZA",
"id" : 0,
"primary" : true
},
"assigned" : true,
"assigned_node_id" : "Qc6VL8c5RWaw1qXZ0Rg57g",
"nodes" : {
"V-Spi0AyRZ6ZvKbaI3691w" : {
"node_name" : "Susan Storm",
"node_attributes" : {

},
"final_decision" : "NO",
"weight" : 1.4499999,
"decisions" : [ {
"decider" : "filter",
"decision" : "NO",
"explanation" : "node does not match index include filters [foo:\"bar\"]"
} ]
},
"Qc6VL8c5RWaw1qXZ0Rg57g" : {
"node_name" : "Slipstream",
"node_attributes" : {
"bar" : "baz",
"foo" : "bar"
},
"final_decision" : "CURRENTLY_ASSIGNED",
"weight" : 0.0,
"decisions" : [ {
"decider" : "same_shard",
"decision" : "NO",
"explanation" : "the shard cannot be allocated on the same node id [Qc6VL8c5RWaw1qXZ0Rg57g] on which it already exists"
} ]
},
"PzdyMZGXQdGhqTJHF_hGgA" : {
"node_name" : "The Symbiote",
"node_attributes" : { },
"final_decision" : "NO",
"weight" : 3.6999998,
"decisions" : [ {
"decider" : "filter",
"decision" : "NO",
"explanation" : "node does not match index include filters [foo:\"bar\"]"
} ]
}
}
}
```
Only "NO" decisions are returned by default, but all decisions can be
shown by specifying the `?include_yes_decisions=true` parameter in the
request.

Node roles are now serialized as well, they are not part of the node attributes anymore. DiscoveryNodeService takes care of dividing settings into attributes and roles. DiscoveryNode always requires to pass in attributes and roles separately.
Primary terms is a way to make sure that operations replicated from stale primary are rejected by shards following a newly elected primary.
Original PRs adding this to the seq# feature branch #14062 , #14651 . Unlike those PR, here we take a different approach (based on newer code in master) where the primary terms are stored in the meta data only (and not in `ShardRouting` objects).

Change version, required a minor fix in the RPM building.
In case of a alpha/beta version, the release will contain alpha/beta
as the RPM version cannot contains dashes/tildes.
The fielddata settings in mappings have been refatored so that:
- text and string have a `fielddata` (boolean) setting that tells whether it
is ok to load in-memory fielddata. It is true by default for now but the
plan is to make it default to false for text fields.
- text and string have a `fielddata_frequency_filter` which contains the same
thing as `fielddata.filter.frequency` used to (but validated at parsing time
instead of being unchecked settings)
- regex fielddata filtering is not supported anymore and will be dropped from
mappings automatically on upgrade.
- text, string and _parent fields have an `eager_global_ordinals` (boolean)
setting that tells whether to load global ordinals eagerly on refresh.
- in-memory fielddata is not supported on keyword fields anymore at all.
- the `fielddata` setting is not supported on other fields that text and string
and will be dropped when upgrading if specified.
this is the last step to remove node level service from IndexShard.
This means that tests can now more easily create an IndexShard instance
without starting a node and removes the dependency between IndexShard and Client/ScriptService
We current have a ClusterService interface, implemented by InternalClusterService and a couple of test classes. Since the decoupling of the transport service and the cluster service, one can construct a ClusterService fairly easily, so we don't need this extra indirection.
Closes#17183
Also replaced the PercolatorQueryRegistry with the new PercolatorQueryCache.
The PercolatorFieldMapper stores the rewritten form of each percolator query's xcontext
in a binary doc values field. This make sure that the query rewrite happens only during
indexing (some queries for example fetch shapes, terms in remote indices) and
the speed up the loading of the queries in the percolator query cache.
Because the percolator now works inside the search infrastructure a number of features
(sorting fields, pagination, fetch features) are available out of the box.
The following feature requests are automatically implemented via this refactoring:

Today we allow to set all kinds of index level settings on the node level which
is error prone and difficult to get right in a consistent manner.
For instance if some analyzers are setup in a yaml config file some nodes might
not have these analyzers and then index creation fails.
Nevertheless, this change allows some selected settings to be specified on a node level
for instance:
* `index.codec` which is used in a hot/cold node architecture and it's value is really per node or per index
* `index.store.fs.fs_lock` which is also dependent on the filesystem a node uses
All other index level setting must be specified on the index level. For existing clusters the index must be closed
and all settings must be updated via the API on each of the indices.
Closes#16799
Without this commit fetching the status of a reindex from a node that isn't
coordinating the reindex will fail. This commit properly registers reindex's
status so this doesn't happen. To do so it moves all task status registration
into NetworkModule and creates a method to register other statuses which the
reindex plugin calls.
The build currently uses the old maven support in gradle. This commit
switches to use the newer maven-publish plugin. This will allow future
changes, for example, easily publishing to artifactory.
An additional part of this change makes publishing of build-tools part
of the normal publishing, instead of requiring a separate upload step
from within buildSrc. That also sets us up for a follow up to enable
precomit checks on the buildSrc code itself.
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".
The ingest stats include the following statistics:
* `ingest.total.count`- The total number of document ingested during the lifetime of this node
* `ingest.total.time_in_millis` - The total time spent on ingest preprocessing documents during the lifetime of this node
* `ingest.total.current` - The total number of documents currently being ingested.
* `ingest.total.failed` - The total number ingest preprocessing operations failed during the lifetime of this node
Also these stats are returned on a per pipeline basis.
Currently, the cluster service is tightly coupled to the transport service by both managing node connections and requiring the bound address in order to create the local disco node. This commit introduces a new NodeConnectionsService which is in charge of node connection management and makes it possible to remove all network related calls from the cluster service. The local DiscoNode is now created by DiscoveryNodeService and is set both the cluster service and the transport service during node start up.
Closes#16788Closes#16872
Use index UUID to lookup indices on IndicesService
Today we use the index name to lookup index instances on the IndicesService
which applied to search requests but also to index deletion etc. This commit
moves the interface to expect an Index instance which is a tuple
and looks up the index by uuid rather than by name. This prevents accidental modification
of the wrong index if and index is recreated or searching from the wrong index in such a case.
Accessing an index that has the same name but different UUID will now result in an IndexNotFoundException.

_wait_for_completion defaults to false. If set to true then the API will
wait for all the tasks that it finds to stop running before returning. You
can use the timeout parameter to prevent it from waiting forever. If you
don't set a timeout parameter it'll default to 30 seconds.
Also adds a log message to rest tests if any tasks overrun the test. This
is just a log (instead of failing the test) because lots of tasks are run
by the cluster on its own and they shouldn't cause the test to fail. Things
like fetching disk usage from the other nodes, for example.
Switches the request to getter/setter style methods as we're going that
way in the Elasticsearch code base. Reindex is all getter/setter style.

update to lucene 6 jars
This commit simplifies and consolidates the two different
implementations of terminals used in tests. There is now a single
MockTerminal which captures output, and allows accessing as one large
string (with unix style \n as newlines), as well as configuring
input.
No changes were really needed in our test infra as it didn't use `node.client`. Yet it didn't take into account ingest nodes, what we used to call client nodes in InternalTestCluster were actually ingest only nodes, which now become coordinating only nodes.
Also renamed some method to get rid of the node client terminology as much as possible in favour or coordinating only node.
As discussed in #16565, the node.client setting is an unnecessary shortcut to node.data: false and node.master: false. We have places where we treat nodes with node.client set to true differently compared to master false and data false, which is not correct. Also, with the addition of node.ingest or potentially new roles, it becomes confusing to figure out if a node client should support ingestion or not.
This commit removes the node.client setting in favour being explicit using node.master, node.data and node.ingest instead.
This commit modifies TransportBulkAction to use relative time instead of
absolute time when measuring how long a bulk request took to be
processed, and adds tests for this functionality.
Closes#16916
The big win here is catching tests that are incorrectly named and will
be skipped by gradle, providing a false sense of security.
The whole thing takes about 10 seconds on my Macbook Air, not counting
compiling the test classes, which seems worth it. Because this runs as
a gradle task with propery UP-TO-DATE handling it can be skipped if the
tests haven't been changed which should save some time.
I chose to keep this in test:framework rather than a new subproject of
buildSrc because ESIntegTestCase and doesn't inroduce any additional
dependencies.
DiscoveryService was a bridge into the discovery universe. This is unneeded and we can just access discovery directly or do things in a different way.
One of those different ways, is not having a dedicated discovery implementation for each our dicovery plugins but rather reuse ZenDiscovery.
UnicastHostProviders are now classified by discovery type, removing unneeded checks on plugins.

Instead of modifying methods each time we need to add a new behavior for settings, we can simply pass `SettingsProperty... properties` instead.
`SettingsProperty` could be defined then:
```
public enum SettingsProperty {
Filtered,
Dynamic,
ClusterScope,
NodeScope,
IndexScope
// HereGoesYours;
}
```
Then in setting code, it become much more flexible.
TODO: Note that we need to validate SettingsProperty which are added to a Setting as some of them might be mutually exclusive.
This commit works around an issue with hostname verification in HttpClient when using IPv6
addresses in URLs. When an IPv6 address is used in a URL it is typically wrapped with square
brackets. The hostname verifier for HttpClient does not recognize these as valid IPv6 addresses
and instead treats them as a DNS name. We wrap the strict hostname verifier for this version
of HttpClient and strip brackets if we need to.
The corresponding issue in HttpClient is https://issues.apache.org/jira/browse/HTTPCLIENT-1698
but the fix has not been released yet in a stable version.
Currently dynamic mappings propgate through call semantics, where deeper
dynamic mappings are merged into higher level mappings through
return values of recursive method calls. This makese it tricky
to handle multiple updates in the same method, for example when
trying to create parent object mappers dynamically for a field name
that contains dots.
This change makes the api for adding mappers a simple list
of new mappers, and moves construction of the root level mapping
update to the end of doc parsing.
Today we might start a node and some of the paths might not have the
required permissions. This commit goes through all data directories as
well as index, shard and state directories and ensures we have write access.
To make this work across all OS etc. we are trying to write a real file
and remove it again in each of those directories
Today we have the notion of a snapshot inside Version.java which makes
releasing complicated since to do a release Version.java must be changed.
This commit removes all notions of snapshot from the code and allows to
switch between snapshot and release build by specifying a system property on
the build. For instance running:
```
gradle run -Dbuild.snapshot=false
```
will build and package a release build while the default always
builds snapshots. Calls to the main rest action will still get the snapshot
information rendered out with the response.
This commit moves IndicesRequestCache into o.e.indics and makes all API in this
class package private. All references to SearchReqeust, SearchContext etc. have been factored
out and relevant glue code has been added to IndicesService. The IndicesRequestCache is not a
simple class without any hard dependencies on ThreadPool nor SearchService or IndexShard. This now
allows to add unittests.
This commit also removes two settings `indices.requests.cache.clean_interval` and `indices.fielddata.cache.clean_interval`
in favor of `indices.cache.clean_interval` which cleans both caches.
this is a minor cleanup that detaches `IndicesRequestCache` and `IndicesQueryCache`
from guice and moves it into `IndicesService`. It also decouples the `IndexShard` and `IndexService`
from these caches which are unnecessary dependencies.
