Replicated closed indices can't be indexed into or searched, and therefore don't need a shard with
full indexing and search capabilities allocated. We can save on a lot of heap memory for those
indices by not allocating a mapper service and caching infrastructure (which preallocates a constant
amount per instance). Before this change, a 1GB ES instance could host 250 replicated closed
metricbeat indices (each index with one shard). After this change, the same instance can host 7300
replicated closed metricbeat instances (not that this would be a recommended configuration). Most
of the remaining memory is in the cluster state and the IndexSettings object.
Previously, `getTime(colIdx/colLabel)` and
`getObject(colIdx/colLabel, java.sql.Time.class)` methods were computing
the time from a `ZonedDateTime` by applying day in millis modulo on the epoch millis
of the `ZonedDateTime` object. This is wrong as we need to keep the time
related fields at the timezone of the `ZonedDateTime` object and just
set the date info to the epoch date (01/01/1970).
Additionally fixes a testing issue as the original timezone id is converted
to an offset string when parsing the response from the server.

Right now, the stats API only provides refresh metrics regarding
internal refreshes. This isn't very useful and somewhat misleading for
cluster administrators since the internal refreshes are not indicative
of documents being available for search.
In this PR I added a new metric for collecting external refreshes as
they occur and exposing them through the stats API. Now, calling an
endpoint for stats will yield external refresh metrics as well.

Previously, `getDate(int columnIdx)/getDate(String columnLabel)` and
were using legacy`java.util.Calendar` instead of the the `java.time.*`
classes to reset to the start of day. This resulted in different results
for certain timestamps and timezones when calling
`getDate(col)` vs`getObject(col, java.sql.Date)`
Now only the methods (that must be implemented due to the JDBC spec)
`getDate(int columnIdx, Calendar cal)/getDate(String columnLabel, Calendar cal)`

In some cases, a request to perform a retention lease action can arrive
on a primary shard before it is active. In this case, the primary shard
would not yet be in primary mode, tripping an assertion in the
replication tracker. Instead, we should not attempt to perform such
actions on an initializing shard. This commit addresses this by not
returning the primary shard in the single shard iterator if the primary
shard is not yet active.
Previously metric aggregations on date fields would return a double

This refactoring is in the context of the work related to moving security
tokens to a new index. In that regard, the Token Service has to work with
token documents stored in any of the two indices, albeit only as a transient
situation. I reckoned the added complexity as unmanageable,
hence this refactoring.
This is incomplete, as it fails to address the goal of minimizing .security accesses,
but I have stopped because otherwise it would've become a full blown rewrite
(if not already). I will follow-up with more targeted PRs.
In addition to being a true refactoring, some 400 errors moved to 500. Furthermore,
more stringed validation of various return result, has been implemented, notably the
one of the token document creation.
This commit adjusts the frequency with which CCR renews retention leases

Lucene reclaim soft-deleted documents more aggressively, which we have

When creating API keys we check for if API key with

This commit fixes by executing search action with SECURITY_ORIGIN
so it can be executed with XPackSecurityUser.
Also fixed the Rest test to avoid using a user with `super_user` role.

Some field types are not used for queries which use auto-expansion, in

of those types, with the count returned by the deprecation check being

When shutting down a node, auto-followers will keep trying to run. This
is happening even as transport services and other components are being
closed. In some cases, this can lead to a stack overflow as we rapidly
try to check the license state of the remote cluster, can not because
the transport service is shutdown, and then immeidately retry
again. This can happen faster than the shutdown, and we die with stack
overflow. This commit adds a stop command to auto-followers so that this
retry loop occurs at most once on shutdown.
This commit enables full-cluster-restart and rolling-upgrade tests
to run with nodes using a JVM in fips approved only node by using

Previously, JDBC's REST call to the server was always sending UTC
instead of the timezone passed through connection string/properties.
Moreover the conversion to java.sql.Date was problematic as a
calculation on the epoch millis was used to set the time to 00:00:00.000
and the timezone info was lost. This caused the resulting java.sql.Date
object which is always using the JVM's timezone (no matter what timezone
setting is used in the connection string/properties) to be wrongly created.

The problem here was that `DatafeedJob` was updating the last end time searched
based on the `now` even though when there are aggregations, the extactor will
only search up to the floor of `now` against the histogram interval.
This commit fixes the issue by using the end time as calculated by the extractor.
It also adds an integration test that uses aggregations. This test would fail
before this fix. Unfortunately the test is slow as we need to wait for the

When following the steps mentioned in upgrade guide
https://www.elastic.co/guide/en/elastic-stack/6.6/upgrading-elastic-stack.html
if we disable the cluster shard allocation but fail to enable it after
upgrading the nodes and plugins, the next step of upgrading internal
indices fails. As we did not check the bulk request response for reindexing,
we delete the old index assuming it has been created. This is fatal
as we cannot recover from this state.
This commit adds a pre-upgrade check to test the cluster shard
allocation setting and fail upgrade if it is disabled. In case there
are search or bulk failures then we remove the read-only block and
fail the upgrade index request.

The LDAP tests attempt to bind all interfaces,
but if for some reason an interface can't be bound

This allows the test to continue even in more antagonistic

Indices with very large numbers of fields (>1024 by default) that do not

This also adds a deprecation check for index templates with field counts
that would trigger these query failures as well.
When a query is translated into script terms agg where key has a date
type, it should generate a terms agg with value_type long instead of
date, otherwise the key gets formatted as a string, which confuses

The monitoring bulk API accepts the same format as the bulk API, yet its concept

new flag that allows to configure whether usage of `_type` should emit a warning
or not. Support for payloads has been removed for simplicity since they were

The watcher stats implementation tries to look at all queued watches
before preparing the result. We want to cast these to a
WatchExecutionTask to extract the context to prepare the stats for
queued watches. The problem is that not all tasks on the watcher queue
were WatchExecutionTask. This is because a manually executed watch was
not even at all wrapped in a WatchExecutionTask. Moreover, we were using
ExecutorService#submit(Runnable) which would wrap the Runnable in a
FutureTask<?>. This commit addresses this by using a WatchExecutionTask,
and also using ExecutorService#execute(Runnable) so that no wrapping
occurs. This will let us continue with the assumption that all queued
tasks are WatchExecutionTasks.
* Bundle java in distributions
Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.
This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.

managed template it does not always go through the REST
layer for it's internal representation. The internal
representation requires the default "_doc" type, which for
external templates is added in the REST layer.

When trace logging is enabled we log the computed steps for a policy. This
commit makes sure that the steps that are logged are in the same order they will
be run when the policy executes. This makes it much easier to reason about the
policy if the move-to-step API is ever required in the future.
A TLS handshake requires exchanging multiple messages to initiate a
session. If one side decides to close during the handshake, it is
supposed to send a close_notify alert (similar to closing during
application data exchange). The java SSLEngine engine throws an
exception when this happens. We currently log this at the warn level if
trace logging is not enabled. This level is too high for a valid
scenario. Additionally it happens all the time in tests (quickly closing
and opened transports). This commit changes this to be logged at the
debug level if trace is not enabled. Additionally, it extracts the
transport security exception handling to a common class.
This commit introduces the forget follower API. This API is needed in cases that
unfollowing a following index fails to remove the shard history retention leases
on the leader index. This can happen explicitly through user action, or
implicitly through an index managed by ILM. When this occurs, history will be
retained longer than necessary. While the retention lease will eventually
expire, it can be expensive to allow history to persist for that long, and also
prevent ILM from performing actions like shrink on the leader index. As such, we
introduce an API to allow for manual removal of the shard history retention
leases in this case.
Previously all the threads were writing the received tokens to a
HashSet. In cases with many threads, sometimes (1 every ~25 tests)
calling size() on the HashSet returned 2 even though it seemed to
contain only one String and there was no evidence from logging that
threadSecurityClient.refreshToken() ever returned a different
access or refresh token.
This commit changes the test to use a ConcurrentHashMap instead,
checking that we only received one pair of access token/refresh token
eventually. It also adds a check so that we won't take into consideration
tokens that are returned after 30s, hence not in the concurrent refresh
time window.
Due to migration from joda to java.time licence expiration 'full date' format
has to use 4-char pattern (MMMM). Also since jdk9 the date with ROOT
locale will still return abbreviated days and month names.

Fixes several errors of the token retry logic:
* not checking for backoff.hasNext() before calling backoff.next()
* checking for backoff.hasNext() without calling backoff.next()
* not preserving the context on the retry
* calling scheduleWithFixedDelay instead of schedule
This change does the following:
1. Makes the per-node setting xpack.ml.max_open_jobs
into a cluster-wide dynamic setting
2. Changes the job node selection to continue to use the
per-node attributes storing the maximum number of open
jobs if any node in the cluster is older than 7.1, and
use the dynamic cluster-wide setting if all nodes are on
7.1 or later
3. Changes the docs to reflect this
4. Changes the thread pools for native process communication
from fixed size to scaling, to support the dynamic nature
of xpack.ml.max_open_jobs
5. Renames the autodetect thread pool to the job comms
thread pool to make clear that it will be used for other
types of ML jobs (data frame analytics in particular)

Today the `GroupedActionListener` accepts a `defaults` parameter but all
callers pass an empty list. Also it is permitted to pass an empty group but
this is trappy because the delegated listener is never be called in that case.
This commit removes the `defaults` parameter and forbids an empty group.
As we are moving to single type indices,
we need to address this change in security-related indexes.
To address this, we are
- updating index templates to use preferred type name `_doc`
- updating the API calls to use preferred type name `_doc`
Upgrade impact:-
In case of an upgrade from 6.x, the security index has type
`doc` and this will keep working as there is a single type and `_doc`
works as an alias to an existing type. The change is handled in the
`SecurityIndexManager` when we load mappings and settings from
the template. Previously, we used to do a `PutIndexTemplateRequest`
with the mapping source JSON with the type name. This has been
modified to remove the type name from the source.
So in the case of an upgrade, the `doc` type is updated
whereas for fresh installs `_doc` is updated. This happens as
backend handles `_doc` as an alias to the existing type name.
An optional step is to `reindex` security index and update the
type to `_doc`.
Since we do not support the security audit log index,
that template has been deleted.

This commit renames the retention lease setting
index.soft_deletes.retention.lease so that it is under the namespace
index.soft_deletes.retention_lease. As such, we rename the setting to
index.soft_deletes.retention_lease.period.
Previously, Watcher only attached its listener to indices that started
with the prefix `.watches`, which causes Watcher to silently fail to
schedule newly created Watches if the `.watches` alias is redirected to
an index that does not start with `.watches`.
Watcher now attaches the listener to all indices, so that Watcher can
respond to changes in which index has the `.watches` alias.
Also adjusts the tests to randomly use non-prefixed concrete indices
for .watches and .triggered_watches.
This change adds two new cluster privileges:
* manage_data_frame_transforms
* monitor_data_frame_transforms
And two new built-in roles:
* data_frame_transforms_admin
* data_frame_transforms_user
These permit access to the data frame transform endpoints.
(Index privileges are also required on the source and
destination indices for each data frame transform, but
since these indices are configurable they it is not
appropriate to grant them via built-in roles.)
Today we have no chance to fetch actual segment stats for segments that
are currently unloaded. This is relevant in the case of frozen indices.
This allows to monitor how much memory a frozen index would use if it was
unfrozen.

This change adds support for the concurrent refresh of access
tokens as described in #36872
In short it allows subsequent client requests to refresh the same token that
come within a predefined window of 60 seconds to be handled as duplicates
of the original one and thus receive the same response with the same newly
issued access token and refresh token.
In order to support that, two new fields are added in the token document. One
contains the instant (in epoqueMillis) when a given refresh token is refreshed
and one that contains a pointer to the token document that stores the new
refresh token and access token that was created by the original refresh.
A side effect of this change, that was however also a intended enhancement
for the token service, is that we needed to stop encrypting the string
representation of the UserToken while serializing. ( It was necessary as we
correctly used a new IV for every time we encrypted a token in serialization, so
subsequent serializations of the same exact UserToken would produce
different access token strings)
This change also handles the serialization/deserialization BWC logic:
In mixed clusters we keep creating tokens in the old format and
consume only old format tokens
In upgraded clusters, we start creating tokens in the new format but
still remain able to consume old format tokens (that could have been
created during the rolling upgrade and are still valid)
When reading/writing TokensInvalidationResult objects, we take into
consideration that pre 7.1.0 these contained an integer field that carried
the attempt count
Resolves#36872
Previously, the security index could be wrongfully recreated. This might
happen if the index was interpreted as missing, as in the case of a fresh
install, but the index existed and the state did not yet recover.
This fix will return HTTP SERVICE_UNAVAILABLE (503) for requests that
try to write to the security index before the state has not been recovered yet.
Investigating how to make DeleteExpiredDataIT faster, it was
revealed that the security audit trail threads were quite hot.
Disabling that seems to be helping quite a bit with making this

Backport support for replicating closed indices (#39499)
Before this change, closed indexes were simply not replicated. It was therefore
possible to close an index and then decommission a data node without knowing
that this data node contained shards of the closed index, potentially leading to
data loss. Shards of closed indices were not completely taken into account when
balancing the shards within the cluster, or automatically replicated through shard
copies, and they were not easily movable from node A to node B using APIs like
Cluster Reroute without being fully reopened and closed again.
This commit changes the logic executed when closing an index, so that its shards
are not just removed and forgotten but are instead reinitialized and reallocated on
data nodes using an engine implementation which does not allow searching or
indexing, which has a low memory overhead (compared with searchable/indexable
opened shards) and which allows shards to be recovered from peer or promoted
as primaries when needed.
This new closing logic is built on top of the new Close Index API introduced in
6.7.0 (#37359). Some pre-closing sanity checks are executed on the shards before
closing them, and closing an index on a 8.0 cluster will reinitialize the index shards
and therefore impact the cluster health.
Some APIs have been adapted to make them work with closed indices:
- Cluster Health API
- Cluster Reroute API
- Cluster Allocation Explain API
- Recovery API
- Cat Indices
- Cat Shards
- Cat Health
- Cat Recovery

Currently there are two security tests that specifically target the

into `AbstractSimpleSecurityTransportTestCase` so that the nio transport
will also be tested.
Additionally the work to build transport configurations is moved out of
the netty transport and tested independently.
This changes the name of the internal security index to ".security-7",
but supports indices that were upgraded from earlier versions and use
the ".security-6" name.

on the cluster.

This fix aligns the document with the rest of the spec,

It is possible that the Unfollow API may fail to release shard history
retention leases when unfollowing, so this needs to be handled by the

action simply ignore those failures.

- Fixes TokenBackwardsCompatibilityIT: Existing tests seemed to made
the assumption that in the oneThirdUpgraded stage the master node
will be on the old version and in the twoThirdsUpgraded stage, the
master node will be one of the upgraded ones. However, there is no
guarantee that the master node in any of the states will or will
not be one of the upgraded ones.
This class now tests:
- That we can generate and consume tokens before we start the
rolling upgrade.
- That we can consume tokens generated in the old cluster during
all the stages of the rolling upgrade.
- That while on a mixed cluster, when/if the master node is
upgraded, we can generate, consume and refresh a token
- That after the rolling upgrade, we can consume a token
generated in an old cluster and can invalidate it so that it
can't be used any more.
- Ensures that during the rolling upgrade, the upgraded nodes have
the same configuration as the old nodes. Specifically that the
file realm we use is explicitly named `file1`. This is needed
because while attempting to refresh a token in a mixed cluster
we might create a token hitting an old node and attempt to refresh
it hitting a new node. If the file realm name is not the same, the
refresh will be seen as being made by a "different" client, and
will, thus, fail.
- Renames the Authentication variable we check while refreshing a
token to be clientAuth in order to make the code more readable.

* Add migrate note
With this change, we won't wait for the local checkpoint to advance to
the max_seq_no before starting phase2 of peer-recovery. We also remove
the sequence number range check in peer-recovery. We can safely do these
thanks to Yannick's finding.
The replication group to be used is currently sampled after indexing
into the primary (see `ReplicationOperation` class). This means that
when initiating tracking of a new replica, we have to consider the
following two cases:
- There are operations for which the replication group has not been
sampled yet. As we initiated the new replica as tracking, we know that
those operations will be replicated to the new replica and follow the
typical replication group semantics (e.g. marked as stale when
unavailable).
- There are operations for which the replication group has already been
sampled. These operations will not be sent to the new replica. However,
we know that those operations are already indexed into Lucene and the
translog on the primary, as the sampling is happening after that. This
means that by taking a snapshot of Lucene or the translog, we will be
getting those ops as well. What we cannot guarantee anymore is that all
ops up to `endingSeqNo` are available in the snapshot (i.e. also see
comment in `RecoverySourceHandler` saying `We need to wait for all
operations up to the current max to complete, otherwise we can not
guarantee that all operations in the required range will be available
for replaying from the translog of the source.`). This is not needed,
though, as we can no longer guarantee that max seq no == local
checkpoint.

Finally! This commit should fix the issues with the CCR retention lease
that has been plaguing build failures. The issue here is that we are
trying to prevent the clear session requests from being executed until
after we have been able to validate that retention leases are being

not blocking them when they are proxied through another node. This
commit addresses that.

This commit changes the sort order of shard stats that are collected in
CCR retention lease integration tests. This change is done so that
primaries appear first in sort order.
This test fails rarely but it is flaky in its current form. The problem
here is that we lack a guarantee on the retention leases having been
synced to all shard copies. We need to sleep long enough to ensure that
that occurs, and then we can sample the retention leases, possibly sleep
again (we usually will not have too since the first sleep will have been
long enough to allow a sync and a renewal to happen, if one was going to
happen), and the sample the retention leases for comparison.
Closes#39331
The shard logged here is the leader shard but it should be the follower
shard since this background retention lease renewal is happening on the
follower side. This commit fixes that.
This commit simplifies the use of transport mocking in the CCR retention
lease integration tests. Instead of adding a send rule between nodes, we
add a default send rule. This greatly simplifies the code here, and
speeds the test up a little bit too.
This fixes#39245. Currently it is possible in this test that the clear
session call times-out. This means that the index commit will not be
released and there will be an assertion triggered in the test teardown.
This commit ensures that we wipe the leader index in the test to avoid
this assertion.
It is okay if the clear session call times-out in normal usage. This
scenario is unavoidable due to potential network issues. We have a local
timeout on the leader to clean it up when this scenario happens.
The assertBusy() that waits the default 10 seconds for a
datafeed to complete very occasionally times out on slow
machines. This commit increases the timeout to 60 seconds.
It will almost never actually take this long, but it's
better to have a timeout that will prevent time being
wasted looking at spurious test failures.
This test should no longer pass when the functionality it is intended to
test is broken, as it now indexes a number of documents and verifies
that the index is staying on the same step until after indexing and
replication of those documents is finished. This prevents the test from
passing if the leader index progresses in its lifecycle during that time.
This test failed once in a very long time with the assertion
that there is no document for the `non_existing_job` in the
state index. I could not see how that is possible and I cannot
reproduce. With this commit the failure message will reveal
some examples of the left behind docs which might shed a light
about what could go wrong.
With this commit we remove all usages of the deprecated method
`ExceptionsHelper#detailedMessage` in tests. We do not address
production code here but rather in dedicated follow-up PRs to keep the
individual changes manageable.

The SchedulerEngine is used in several places in our code and not all

Sleeps in tests smell funny, and we try to avoid them to the extent
possible. We are using a small one in a CCR test. This commit clarifies
the purpose of that sleep by adding a comment explaining it. We also
removed a hard-coded value from the test, that if we ever modified the
value higher up where it was set, we could end up forgetting to change
the value here. Now we ensure that these would move in lock step if we
ever maintain them later.
We have some CCR tests where we use mock transport send rules to control
the behavior that we desire in these tests. Namely, we want to simulate
an exception being thrown on the leader side, or a variety of other
situations. These send rules were put in place between the data nodes on
each side. However, it might not be the case that these requests are
being sent between data nodes. For example, a request that is handled on
a non-data master node would not be sent from a data node. And it might
not be the case that the request is sent to a data node, as it could be
proxied through a non-data coordinating node. This commit addresses this
by putting these send rules in places between all nodes on each side.
Closes#39011Closes#39201
`ReadOnlyEngine` never recovers operations from translog and never
updates translog information in the index shard's recovery state, even
though the recovery state goes through the `TRANSLOG` stage during
the recovery. It means that recovery information for frozen shards indicates
an unkown number of recovered translog ops in the Recovery APIs
(translog_ops: `-1` and translog_ops_percent: `-1.0%`) and this is confusing.
This commit changes the `recoverFromTranslog()` method in `ReadOnlyEngine`
so that it always recover from an empty translog snapshot, allowing the recovery
state translog information to be correctly updated.
