Joost Rothweiler 02a611663a Indices PUT Mapping API docs: Remove mapping type user and rephrase first sentence (#28998)
The current docs on [Indices APIs: PUT Mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html) suggests that a having number of different mapping types per index is still possible in elasticsearch versions > 6.0.0 although they have been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html). The console code has already been updated accordingly but notes (2) and (3) on the console code still name the `user` mapping type.

This PR updates the list with notes after the console code, as well as the first sentence of the docs
to avoid confusion. Also, I have removed the second command from the console code as it no
longer holds any value if the docs are solely on the `_doc` mapping.

Simplify the Translog constructor by always expecting an existing translog (#28676)
Currently the Translog constructor is capable both of opening an existing translog and creating a
new one (deleting existing files). This PR separates these two into separate code paths. The
constructors opens files and a dedicated static methods creates an empty translog.

Allow `_doc` as a type. (#27816)
Allowing `_doc` as a type will enable users to make the transition to 7.0
smoother since the index APIs will be `PUT index/_doc/id` and `POST index/_doc`.
This also moves most of the documentation to `_doc` as a type name.

Limit the number of tokens produced by _analyze (#27529)
Add an index level setting `index.analyze.max_token_count` to control
the number of generated tokens in the  _analyze endpoint.
Defaults to 10000.

Throw an error if the number of generated tokens exceeds this limit.

Automatically prepare indices for splitting (#27451)
Today we require users to prepare their indices for split operations.
Yet, we can do this automatically when an index is created which would
make the split feature a much more appealing option since it doesn't have
any 3rd party prerequisites anymore.

This change automatically sets the number of routinng shards such that
an index is guaranteed to be able to split once into twice as many shards.
The number of routing shards is scaled towards the default shard limit per index
such that indices with a smaller amount of shards can be split more often than
larger ones. For instance an index with 1 or 2 shards can be split 10x
(until it approaches 1024 shards) while an index created with 128 shards can only
be split 3x by a factor of 2. Please note this is just a default value and users
can still prepare their indices with `index.number_of_routing_shards` for custom
splitting.

NOTE: this change has an impact on the document distribution since we are changing
the hash space. Documents are still uniformly distributed across all shards but since
we are artificually changing the number of buckets in the consistent hashign space
document might be hashed into different shards compared to previous versions.

This is a 7.0 only change.

Simon Willnauer bd7efa908a Add ability to split shards (#26931)
This change adds a new `_split` API that allows to split indices into a new
index with a power of two more shards that the source index.  This API works
alongside the `_shrink` API but doesn't require any shard relocation before
indices can be split.

The split operation is conceptually an inverse `_shrink` operation since we
initialize the index with a _syntetic_ number of routing shards that are used
for the consistent hashing at index time. Compared to indices created with
earlier versions this might produce slightly different shard distributions but
has no impact on the per-index backwards compatibility.  For now, the user is
required to prepare an index to be splittable by setting the
`index.number_of_routing_shards` at index creation time.  The setting allows the
user to prepare the index to be splittable in factors of
`index.number_of_routing_shards` ie. if the index is created with
`index.number_of_routing_shards: 16` and `index.number_of_shards: 2` it can be
split into `4, 8, 16` shards. This is an intermediate step until we can make
this the default. This also allows us to safely backport this change to 6.x.

The `_split` operation is implemented internally as a DeleteByQuery on the
lucene level that is executed while the primary shards execute their initial
recovery. Subsequent merges that are triggered due to this operation will not be
executed immediately. All merges will be deferred unti the shards are started
and will then be throttled accordingly.

This change is intended for the 6.1 feature release but will not support pre-6.1
indices to be split unless these indices have been shrunk before. In that case
these indices can be split backwards into their original number of shards.

Boaz Leskes 1ca0b5e9e4 Introduce a History UUID as a requirement for ops based recovery (#26577)
The new ops based recovery, introduce as part of  #10708, is based on the assumption that all operations below the global checkpoint known to the replica do not need to be synced with the primary. This is based on the guarantee that all ops below it are available on primary and they are equal. Under normal operations this guarantee holds. Sadly, it can be violated when a primary is restored from an old snapshot. At the point the restore primary can miss operations below the replica's global checkpoint, or even worse may have total different operations at the same spot. This PR introduces the notion of a history uuid to be able to capture the difference with the restored primary (in a follow up PR).

The History UUID is generated by a primary when it is first created and is synced to the replicas which are recovered via a file based recovery. The PR adds a requirement to ops based recovery to make sure that the history uuid of the source and the target are equal. Under normal operations, all shard copies will stay with that history uuid for the rest of the index lifetime and thus this is a noop. However, it gives us a place to guarantee we fall back to file base syncing in special events like a restore from snapshot (to be done as a follow up) and when someone calls the truncate translog command which can go wrong when combined with primary recovery (this is done in this PR).

We considered in the past to use the translog uuid for this function (i.e., sync it across copies) and thus avoid adding an extra identifier. This idea was rejected as it removes the ability to verify that a specific translog really belongs to a specific lucene index. We also feel that having a history uuid will serve us well in the future.

Ali Beyad 4641254ea6 Parameter improvements to Cluster Health API wait for shards (#20223)
* Params improvements to Cluster Health API wait for shards

Previously, the cluster health API used a strictly numeric value
for `wait_for_active_shards`. However, with the introduction of
ActiveShardCount and the removal of write consistency level for
replication operations, `wait_for_active_shards` is used for
write operations to represent values for ActiveShardCount. This
commit moves the cluster health API's usage of `wait_for_active_shards`
to be consistent with its usage in the write operation APIs.

This commit also changes `wait_for_relocating_shards` from a
numeric value to a simple boolean value `wait_for_no_relocating_shards`
to set whether the cluster health operation should wait for
all relocating shards to complete relocation.

Nik Everett 1e587406d8 Fail yaml tests and docs snippets that get unexpected warnings
Adds `warnings` syntax to the yaml test that allows you to expect
a `Warning` header that looks like:
```
    - do:
        warnings:
            - '[index] is deprecated'
            - quotes are not required because yaml
            - but this argument is always a list, never a single string
            - no matter how many warnings you expect
        get:
            index:    test
            type:    test
            id:        1
```

These are accessible from the docs with:
```
// TEST[warning:some warning]
```

This should help to force you to update the docs if you deprecate
something. You *must* add the warnings marker to the docs or the build
will fail. While you are there you *should* update the docs to add
deprecation warnings visible in the rendered results.

Boaz Leskes 6861d3571e Persistent Node Ids (#19140)
Node IDs are currently randomly generated during node startup. That means they change every time the node is restarted. While this doesn't matter for ES proper, it makes it hard for external services to track nodes. Another, more minor, side effect is that indexing the output of, say, the node stats API results in creating new fields due to node ID being used as keys.

The first approach I considered was to use the node's published address as the base for the id. We already [treat nodes with the same address as the same](https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/discovery/zen/NodeJoinController.java#L387) so this is a simple change (see [here](https://github.com/elastic/elasticsearch/compare/master...bleskes:node_persistent_id_based_on_address)). While this is simple and it works for probably most cases, it is not perfect. For example, if after a node restart, the node is not able to bind to the same port (because it's not yet freed by the OS), it will cause the node to still change identity. Also in environments where the host IP can change due to a host restart, identity will not be the same. 

Due to those limitation, I opted to go with a different approach where the node id will be persisted in the node's data folder. This has the upside of connecting the id to the nodes data. It also means that the host can be adapted in any way (replace network cards, attach storage to a new VM). I

It does however also have downsides - we now run the risk of two nodes having the same id, if someone copies clones a data folder from one node to another. To mitigate this I changed the semantics of the protection against multiple nodes with the same address to be stricter - it will now reject the incoming join if a node exists with the same id but a different address. Note that if the existing node doesn't respond to pings (i.e., it's not alive) it will be removed and the new node will be accepted when it tries another join.

Last, and most importantly, this change requires that *all* nodes persist data to disk. This is a change from current behavior where only data & master nodes store local files. This is the main reason for marking this PR as breaking.

Other less important notes:
- DummyTransportAddress is removed as we need a unique network address per node. Use `LocalTransportAddress.buildUnique()` instead.
- I renamed `node.add_lid_to_custom_path` to `node.add_lock_id_to_custom_path` to avoid confusion with the node ID which is now part of the `NodeEnvironment` logic.
- I removed the `version` paramater from `MetaDataStateFormat#write` , it wasn't really used and was just in the way :)
- TribeNodes are special in the sense that they do start multiple sub-nodes (previously known as client nodes). Those sub-nodes do not store local files but derive their ID from the parent node id, so they are generated consistently.

Simon Willnauer b2c4c323e1 Allow `_shrink` to N shards if source shards is a multiple of N (#18699)
Today we allow to shrink to 1 shard but that might not be possible due to
too many document or a single shard doesn't meet the requirements for the index.
The logic can be expanded to N shards if the source index shards is a multiple of N.
This guarantees that there are not hotspots created due to different number of shards
being shrunk into one.

Today we use `index.routing.allocation.include._id` to filter the allocation

delete that setting / change it once the primary has been recovered (shrink is done)
This PR adds a dedicated filter that can only be set internally that only filters
allocation for unassigned shards.

Simon Willnauer 502a775a7c Add primitive to shrink an index into a single shard (#18270)
This adds a low level primitive operations to shrink an existing
index into a new index with a single shard. This primitive expects
all shards of the source index to allocated on a single node. Once the target index is initializing on the shrink node it takes a snapshot of the source index shards and copies all files into the target indices data folder. An [optimization](https://issues.apache.org/jira/browse/LUCENE-7300) coming in Lucene 6.1 will also allow for optional constant time copy if hard-links are supported by the filesystem. All mappings are merged into the new indexes metadata once the snapshots have been taken on the merge node.

To shrink an existing index all shards must be moved to a single node (one instance of each shard) and the index must be read-only:

```BASH
$ curl -XPUT 'http://localhost:9200/logs/_settings' -d '{
    "settings" : {
        "index.routing.allocation.require._name" : "shrink_node_name",
        "index.blocks.write" : true 
    }
}
```
once all shards are started on the shrink node. the new index can be created via:

```BASH
$ curl -XPUT 'http://localhost:9200/logs/_shrink/logs_single_shard' -d '{
    "settings" : {
        "index.codec" : "best_compression",
        "index.number_of_replicas" : 1
    }
}'
```

This API will perform all needed check before the new index is created and selects the shrink node based on the allocation of the source index. This call returns immediately, to monitor shrink progress the recovery API should be used since all copy operations are reflected in the recovery API with byte copy progress etc.

The shrink operation does not modify the source index, if a shrink operation should
be canceled or if the shrink failed, the target index can simply be deleted and
all resources are released.

    "number_of_replicas": 1,
    "data_path": "/tmp/foo/bar/baz",

Adrien Grand 38f5cc236a Rename caches.
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

Boaz Leskes 26d71fe00e Reduce shard inactivity timeout to 5m
To better distribute the memory allocating to indexing, the IndexingMemoryController periodically checks the different shard for their last indexing activity. If no activity has happened for a while, the controller marks the shards as in active and allocated it's memory buffer budget (but a small minimal budget) to other active shards. The recently added synced flush feature (#11179, #11336) uses this inactivity trigger to attempt as a trigger to attempt adding a sync id marker (which will speed up future recoveries).

We wait for 30m before declaring a shard inactive. However, these days the operation just requires a refresh and is light. We can be stricter (and 5m) increase the chance a synced flush will be triggered.

In #11072 we are adding a check that will prevent opening of old indices. However, this check doesn't take into consideration the fact that indices can be made compatible with the current version through upgrade API. In order to make compatibility check aware of the upgrade, the upgrade API should write a new setting `index.version.minimum_compatible` that will indicate the minimum compatible version of lucene this index is compatible with and `index.version.upgraded` that will indicate the version of elasticsearch that performed the upgrade.

Boaz Leskes b376a3fbfb Move index sealing terminology to synced flush
#10032 introduced the notion of sealing an index by marking it with a special read only marker, allowing for a couple of optimization to happen. The most important one was to speed up recoveries of shards where we know nothing has changed since they were online by skipping the file based sync phase. During the implementation we came up with a light notion which achieves the same recovery benefits but without the read only aspects which we dubbed synced flush. The fact that it was light weight and didn't put the index in read only mode, allowed us to do it automatically in the background which has great advantage. However we also felt the need to allow users to manually trigger this operation.

 The implementation at #11179 added the sync flush internal logic and the manual (rest) rest API. The name of the API was modeled after the sealing terminology which may end up being confusing. This commit changes the API name to match the internal synced flush naming, namely `{index}/_flush/synced'.

  On top of that it contains a couple other changes:
   - Remove all java client API. This feature is not supposed to be called programtically by applications but rather by admins.
   - Improve rest responses making structure similar to other (flush) API
   - Change IndexShard#getOperationsCount to exclude the internal +1 on open shard . it's confusing to get 1 while there are actually no ongoing operations
   - Some minor other clean ups

Adrien Grand 2c241e8a36 Mappings: Remove the `ignore_conflicts` option.
Mappings conflicts should not be ignored. If I read the history correctly, this
option was added when a mapping update to an existing field was considered a
conflict, even if the new mapping was exactly the same. Now that mapping updates
are smart enough to detect conflicting options, we don't need an option to
ignore conflicts.

* 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

Michael McCandless 399f0ccce9 Core: add only_ancient_segments to upgrade API, so only segments with an old Lucene version are upgraded
This option defaults to false, because it is also important to upgrade
the "merely old" segments since many Lucene improvements happen within
minor releases.

But you can pass true to do the minimal work necessary to upgrade to
the next major Elasticsearch release.

The HTTP GET upgrade request now also breaks out how many bytes of
ancient segments need upgrading.

Ryan Ernst 693d91e41c Mappings: Remove delete mapping API
Deleting a type from an index is inherently dangerous because
the type can be recreated with new mappings which may conflict
with existing segments still using the old mappings. This
removes the ability to delete a type (similar to how deleting
fields within a type is not allowed, for the same reason).

Al Lefebvre 94f82368f0 Update templates.asciidoc
I've been attempting to programatically verify that adding index templates via the `{path.conf}/templates/` directory works fine although I was never able to validate this via an API call to the `/_template/`.  It seems that these templates do not appear in that API call, which I discovered in the following mail thread:

http://elasticsearch-users.115913.n3.nabble.com/Loading-of-index-settings-template-from-file-in-config-templates-td4024923.html#d1366317284000-912

My question is why wouldn't the `/_template/*` method return these templates?  This tends to complicate things for those that want to perform automated tests to verify that they are in fact being recognized and used by Elasticsearch.

Boaz Leskes 3e32dd985a Recovery: RecoveryState clean up
To support the `_recovery` API, the recovery process keeps track of current progress in a class called RecoveryState. This class currently have some issues, mostly around concurrency (see #6644 ). This PR cleans it up as well as other issues around it:

- Make the Index subsection API cleaner:
- remove redundant information - all calculation is done based on the underlying file map
- clearer definition of what is what: total files, vs reused files (local files that match the source) vs recovered files (copied over). % based progress is reported based on recovered files only.
- cleaned up json response to match other API (sadly this breaks the structure). We now properly report human values for dates and other units.
- Add more robust unit testing
- Detail flag was passed along as state (it's now a ToXContent param)
- State lookup during reporting is now always done via the IndexShard , no more fall backs to many other classes.
- Cleanup APIs around time and move the little computations to the state class as opposed to doing them out of the API

I also improved error messages out of the REST testing infra for things I run into.

Ryan Ernst f735baf306 Core: Remove ability to run optimize and upgrade async
This has been very trappy. Rather than continue to allow buggy behavior
of having upgrade/optimize requests sidestep the single shard per node
limits optimize is supposed to be subject to, this removes
the ability to run the upgrade/optimize async.

Adrien Grand 95f46f1212 Docs: Use the new experimental annotation.
We now have a very useful annotation to mark features or parameters as
experimental. Let's use it! This commit replaces some custom text warnings with
this annotation and adds this annotation to some existing features/parameters:
 - inner_hits (unreleased yet)
 - terminate_after (released in 1.4)
 - per-bucket doc count errors in the terms agg (released in 1.4)

I also tagged with this annotation settings which should either be not needed
(like the ability to evict entries from the filter cache based on time) or that
are too deep into the way that Elasticsearch works like the Directory
implementation or merge settings.

Michael McCandless b9358ccca8 Core: switch to auto IO throttle for merges
This adds a new boolean (index.merge.scheduler.auto_throttle) dynamic
setting, default true (matching Lucene), to adaptively set the IO rate
limit for merges over time.

This is more flexible than the previous fixed rate throttling because
it responds depending on the incoming merge rate, so search-heavy
applications that are not doing much indexing will see merges heavily
throttled while indexing-heavy cases will lighten the throttle so
merges can keep up within incoming indexing.

The fixed rate throttling is still available as a fallback if things
go horribly wrong.

Zachary Tong f5b2dfd052 Aliases: Throw exception if index is null or missing when creating an alias
Fixes a bug where alias creation would allow `null` for index name, which thereby
applied the alias to _all_ indices.  This patch makes the validator throw an
exception if the index is null.

```bash
POST /_aliases
{
   "actions": [
      {
         "add": {
            "alias": "empty-alias",
            "index": null
         }
      }
   ]
}
```
```json
{
   "error": "ActionRequestValidationException[Validation Failed: 1: Alias action [add]: [index] may not be null;]",
   "status": 400
}
```

The reason this bug wasn't caught by the existing tests is because
the old test for nullness only validated against a cluster which had
zero indices.  The null index is translated into "_all", and since
there are no indices, this fails because the index doesn't exist.
 So the test passes.

However, as soon as you add an index, "_all" resolves and you get the
situation described in the original bug report:  null index is
accepted by the alias, resolves to "_all" and gets applied to everything.

The REST tests, otoh, explicitly tested this bug as a real feature and therefore
passed.  The REST tests were modified to change this behavior.

Fixes #7863

Simon Willnauer d5c0a49620 [ROUTING] Add rebalance enabled allocation decider
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.
