For FsBlobStore and HdfsBlobStore, if the repository is read only, the blob store should be aware of the readonly setting and do not create directories if they don't exist.
Closes#21495
* Enhances exists queries to reduce need for `_field_names`
Before this change we wrote the name all the fields in a document to a `_field_names` field and then implemented exists queries as a term query on this field. The problem with this approach is that it bloats the index and also affects indexing performance.
This change adds a new method `existsQuery()` to `MappedFieldType` which is implemented by each sub-class. For most field types if doc values are available a `DocValuesFieldExistsQuery` is used, falling back to using `_field_names` if doc values are disabled. Note that only fields where no doc values are available are written to `_field_names`.
Closes#26770
* Addresses review comments
* Addresses more review comments
* implements existsQuery explicitly on every mapper
* Reinstates ability to perform term query on `_field_names`
* Added bwc depending on index created version
* Review Comments
* Skips tests that are not supported in 6.1.0
These values will need to be changed after backporting this PR to 6.x
Currently, when we create a BeiderMorseFilter with an unspecified `languageset`,
the filter will not guess the language, which should be the default behaviour.
This change fixes this and adds a simple test for the cases with and without
provided `languageset` settings.
Closes#26771
Today we return a `String[]` that requires copying values for every
access. Yet, we already store the setting as a list so we can also directly
return the unmodifiable list directly. This makes list / array access in settings
a much cheaper operation especially if lists are large.
Today we represent each value of a list setting with it's own dedicated key
that ends with the index of the value in the list. Aside of the obvious
weirdness this has several issues especially if lists are massive since it
causes massive runtime penalties when validating settings. Like a list of 100k
words will literally cause a create index call to timeout and in-turn massive
slowdown on all subsequent validations runs.
With this change we use a simple string list to represent the list. This change
also forbids to add a settings that ends with a .0 which was internally used to
detect a list setting. Once this has been rolled out for an entire major
version all the internal .0 handling can be removed since all settings will be
converted.

While working on #26751, I found that we are passing the container name on every single method although we don't need it as it is stored within the blobstore object already.
This commit simplifies a bit that part of the code.
It also removes `repositoryName` from AzureBlobStore which was not used anymore.
Also we move some properties in AzureBlobContainer to `private` members.
Since `#getAsMap` exposes internal representation we are trying to remove it
step by step. This commit is cleaning up some xcontent writing as well as
usage in tests
We use group settings historically instead of using a prefix setting which is more restrictive and type safe. The majority of the usecases needs to access a key, value map based on the _leave node_ of the setting ie. the setting `index.tag.*` might be used to tag an index with `index.tag.test=42` and `index.tag.staging=12` which then would be turned into a `{"test": 42, "staging": 12}` map. The group settings would always use `Settings#getAsMap` which is loosing type information and uses internal representation of the settings. Using prefix settings allows now to access such a method type-safe and natively.
Even though you annotate the Test class with `@ThirdParty` the static
code is initialized.
In that case it fails with:
```

* Use Azure upload method instead of our own implementation
We are not following the Azure documentation about uploading blobs to Azure storage. https://docs.microsoft.com/en-us/azure/storage/blobs/storage-java-how-to-use-blob-storage#upload-a-blob-into-a-container
Instead we are using our own implementation which might cause some troubles and rarely some blobs can be not immediately commited just after we close the stream. Using the standard implementation provided by Azure team should allow us to benefit from all the magic Azure SDK team already wrote.
And well... Let's just read the doc!
* Adapt integration tests to secure settings
That was a missing part in #23405.
* Simplify all the integration tests and *extends ESBlobStoreRepositoryIntegTestCase tests
* removes IT `testForbiddenContainerName()` as it is useless. The plugin does not create anymore the container but expects that the user has created it before registering the repository
* merges 2 IT classes so all IT tests are ran from one single class
* We don't remove/create anymore the container between each single test but only for the test suite
While working on #26751 and doing some manual integration testing I found that this #22858 removed an important line of our code:
`AzureRepository` overrides default `initializeSnapshot` method which creates metadata files and do other stuff.
But with PR #22858, I wrote:
```java
@Override
public void initializeSnapshot(SnapshotId snapshotId, List<IndexId> indices, MetaData clusterMetadata) {
if (blobStore.doesContainerExist(blobStore.container()) == false) {
throw new IllegalArgumentException("The bucket [" + blobStore.container() + "] does not exist. Please create it before " +
" creating an azure snapshot repository backed by it.");
}
}
```
instead of
```java
@Override
public void initializeSnapshot(SnapshotId snapshotId, List<IndexId> indices, MetaData clusterMetadata) {
if (blobStore.doesContainerExist(blobStore.container()) == false) {
throw new IllegalArgumentException("The bucket [" + blobStore.container() + "] does not exist. Please create it before " +
" creating an azure snapshot repository backed by it.");
}
super.initializeSnapshot(snapshotId, indices, clusterMetadata);
}
```
As we never call `super.initializeSnapshot(...)` files are not created and we can't restore what we saved.
Closes#26777.
This change adds a fromXContent method to Settings that allows to read
the xcontent that is produced by toXContent. It also replaces the entire settings
loader infrastructure and removes the structured map representation. Future PRs will
also tackle the `getAsMap` that exposes the internal represenation of settings for
better encapsulation.
Add checks for special permissions before reading hdfs stream data. Also adds test from
readonly repository fix. MiniHDFS will now start with an existing repository with a single snapshot
contained within. Readonly Repository is created in tests and attempts to list the snapshots
within this repo.
When adding file based discovery, we added a fallback when the discovery
type was set to zen (the default, so everyone got this warning). This
commit removes the fallback for 6.0. Setting file discovery should now
happen explicitly through the hosts_provider setting.
closes#26661
The discovery-file plugin was not config path aware, so it always picked
up the default config path (from Elasticsearch home) rather than a
custom config path. This commit fixes the discovery-file plugin to
respect a custom config path.
Relates #26662
Initialize the default stop-tags in `KuromojiPartOfSpeechFilterFactory` if the
`stoptags` are not given in the config. Also adding a test which checks that
part-of-speech tokens are removed when using the kuromoji_part_of_speech
filter.
Removing several occurrences of this typo in the docs and javadocs, seems to be
a common mistake. Corrections turn up once in a while in PRs, better to correct
some of this in one sweep.
You can define a proxy using the following settings:
```yml
azure.client.default.proxy.host: proxy.host
azure.client.default.proxy.port: 8888
azure.client.default.proxy.type: http
```
Supported values for `proxy.type` are `direct`, `http` or `socks`. Defaults to `direct` (no proxy).
Closes#23506
BTW I changed a test `testGetSelectedClientBackoffPolicyNbRetries` as it was using an old setting name `cloud.azure.storage.azure.max_retries` instead of `azure.client.azure1.max_retries`.
Follow up for #23405.
We remove azure deprecated settings in 7.0:
* The legacy azure settings which where starting with `cloud.azure.storage.` prefix have been removed.
This includes `account`, `key`, `default` and `timeout`.
You need to use settings which are starting with `azure.client.` prefix instead.
* Global timeout setting `cloud.azure.storage.timeout` has been removed.
You must set it per azure client instead. Like `azure.client.default.timeout: 10s` for example.
This commit contains:
* update AWS SDK for ECS Task IAM support
* ignore dependencies not essential to `discovery-ec2`:
* jmespath seems to be used for `waiters`
* amazon ion is a protocol not used by EC2 or IAM
RangeQueryBuilder needs to perform too many `instanceof` checks in order to
check for `date` or `range` fields in order to know what it should do with the
shape relation, time zone and date format.
This commit adds those 3 parameters to the `rangeQuery` factory method so that
those instanceof checks are not necessary anymore.
This commit adds the Log4j to SLF4J binding JAR to the repository-hdfs
plugin so that SLF4J can detect Log4j at runtime and therefore use the
server Log4j implementation for logging (and the usual Elasticsearch
APIs can be used for setting logging levels).

Calls to Collator.getInstance without arguments returns a
collator that uses the system's default locale, which we don't
want because it makes behavior harder to reproduce. Change it
to always use the root locale instead.
For #25587
* Remove the _all metadata field
This change removes the `_all` metadata field. This field is deprecated in 6
and cannot be activated for indices created in 6 so it can be safely removed in
the next major version (e.g. 7).
This allows plugins to plug rescore implementations into
Elasticsearch. While this is a fairly expert thing to do I've
done my best to point folks to the QueryRescorer as one that at
least documents the tradeoffs that it makes. I've attempted to
limit the API surface area by removing `SearchContext` from the
exposed interface, instead exposing just the IndexSearcher and
`QueryShardContext`. I also tried to make some of the class names
more consistent and do some general cleanup while I was there.
I entertained the notion of moving the `QueryRescorer` to module.
After all, it'd be a wonderful test to prove that you can plug
rescore implementation into Elasticsearch if the only built in
rescore implementation is in the module. But I decided against it
because the new module would require a client jar and it'd require
moving some more things around. I think if we really want to do
it, we should do it as a followup.
I did, on the other hand, create an "example" rescore plugin which
should both be a nice example for anyone wanting to plug in their
own rescore implementation and servers as a good integration test
to make sure that you can indeed plug one in.
Closes#26208
This commit makes the security code aware of the Java 9 FilePermission changes (see #21534) and allows us to remove the `jdk.io.permissionsUseCanonicalPath` system property.
We should have the same behavior for Azure repositories as we have for S3 (see #22762).
Instead of:
```yml
cloud:
azure:
storage:
my_account1:
account: your_azure_storage_account1
key: your_azure_storage_key1
default: true
my_account2:
account: your_azure_storage_account2
key: your_azure_storage_key2
```
Support something like:
```
azure.client:
default:
account: your_azure_storage_account1
key: your_azure_storage_key1
my_account2:
account: your_azure_storage_account2
key: your_azure_storage_key2
```
Then instead of:
```
PUT _snapshot/my_backup3
{
"type": "azure",
"settings": {
"account": "my_account2"
}
}
```
Use:
```
PUT _snapshot/my_backup3
{
"type": "azure",
"settings": {
"config": "my_account2"
}
}
```
If someone uses:
```
PUT _snapshot/my_backup3
{
"type": "azure"
}
```
It will use the `default` azure repository settings.
And mark as deprecated old settings.
Closes#22763.
We introduced a hack in #25885 to respect the cluster alias if available on the `_index` field. This is important if aggregations or other field data related operations are executed. Yet, we added a small hack that duplicated an implementation detail from the `_index` field data builder to make this work. This change adds a necessary but simple API change that allows us to remove the hack and only have a single implementation.
This is related to #25931. In CloudBlobContainer#exists it is possible
that a socket connection will be opened. This commit ensures that those
calls have the proper socket privileges.
This is related to #25932. Currently when we create the
`GoogleCloudStorageService` client we do not wrap that call in a
doPrivileged block. The call might open a connection. This commit
ensures that the creation is wrapped in a doPrivileged block.
