David Roberts 558e323c89 [ML] Introduce a setting for the process connect timeout (#43234)
This change introduces a new setting,
xpack.ml.process_connect_timeout, to enable
the timeout for one of the external ML processes
to connect to the ES JVM to be increased.

The timeout may need to be increased if many
processes are being started simultaneously on
the same machine. This is unlikely in clusters
with many ML nodes, as we balance the processes
across the ML nodes, but can happen in clusters
with a single ML node and a high value for
xpack.ml.node_concurrent_job_allocations.

Yannick Welsch 2049f715b3 Add voting-only master node (#43410)
A voting-only master-eligible node is a node that can participate in master elections but will not act
as a master in the cluster. In particular, a voting-only node can help elect another master-eligible
node as master, and can serve as a tiebreaker in elections. High availability (HA) clusters require at
least three master-eligible nodes, so that if one of the three nodes is down, then the remaining two
can still elect a master amongst them-selves. This only requires one of the two remaining nodes to
have the capability to act as master, but both need to have voting powers. This means that one of
the three master-eligible nodes can be made as voting-only. If this voting-only node is a dedicated
master, a less powerful machine or a smaller heap-size can be chosen for this node. Alternatively, a
voting-only non-dedicated master node can play the role of the third master-eligible node, which
allows running an HA cluster with only two dedicated master nodes.

Closes #14340

Matthew Adams 0bcadbf846 Clarify storage location of ML Snapshots (#43437)
The existing language was misleading about the model snapshots and where they are located. Saying "to disk" sounds like files external to Elasticsearch IMO. It raises the obvious question, where on disk? which node? Is it in the Elasticsearch snapshot repo? The model snapshots are held in an internal index.

Fix GeoIP custom database directory in docs (#43383)
These docs were misleading for package installations of
Elasticsearch. Instead, we should refer to $ES_CONFIG/ingest-geoip as
the path to place the custom database files. For non-package
installations, this is the same as $ES_HOME/config, but for package
installations this is not the case as the config directory for package
installations is /etc/elasticsearch, and is not relative to
$ES_HOME. This commit corrects the docs.

Reindex max_docs parameter name (#42942)
Previously, a reindex request had two different size specifications in the body:
* Outer level, determining the maximum documents to process
* Inside the source element, determining the scroll/batch size.

The outer level size has now been renamed to max_docs to
avoid confusion and clarify its semantics, with backwards compatibility and
deprecation warnings for using size.
Similarly, the size parameter has been renamed to max_docs for
update/delete-by-query to keep the 3 interfaces consistent.

Finally, all 3 endpoints now support max_docs in both body and URL.

* adds the "do not stop half-or-more of the master-eligible nodes" slogan that
  was notably absent.

David Roberts b61202b0a8 [ML] Add a limit on line merging in find_file_structure (#42501)
When analysing a semi-structured text file the
find_file_structure endpoint merges lines to form
multi-line messages using the assumption that the
first line in each message contains the timestamp.
However, if the timestamp is misdetected then this
can lead to excessive numbers of lines being merged
to form massive messages.

This commit adds a line_merge_size_limit setting
(default 10000 characters) that halts the analysis
if a message bigger than this is created.  This
prevents significant CPU time being spent subsequently

James Rodewig f51f8ed04c [DOCS] Remove unneeded options from `[source,sql]` code blocks (#42759)
In AsciiDoc, `subs="attributes,callouts,macros"` options were required
to render `include-tagged::` in a code block.

With elastic/docs#827, Elasticsearch Reference documentation migrated
from AsciiDoc to Asciidoctor.

In Asciidoctor, the `subs="attributes,callouts,macros"` options are no
longer needed to render `include-tagged::` in a code block. This commit
removes those unneeded options.

Julie Tibshirani 1bb505c70d Clarify the settings around limiting nested mappings. (#42686)
* Previously, we mentioned multiple times that each nested object was indexed as its own document. This is repetitive, and is also a bit confusing in the context of `index.mapping.nested_fields.limit`, as that applies to the number of distinct `nested` types in the mappings, not the number of nested objects. We now just describe the issue once at the beginning of the section, to illustrate why `nested` types can be expensive.
* Reference the ongoing example to clarify the meaning of the two settings.

David Roberts f472186b9f [ML] Improve file structure finder timestamp format determination (#41948)
This change contains a major refactoring of the timestamp
format determination code used by the ML find file structure
endpoint.

Previously timestamp format determination was done separately
for each piece of text supplied to the timestamp format finder.
This had the drawback that it was not possible to distinguish
dd/MM and MM/dd in the case where both numbers were 12 or less.
In order to do this sensibly it is best to look across all the
available timestamps and see if one of the numbers is greater
than 12 in any of them.  This necessitates making the timestamp
format finder an instantiable class that can accumulate evidence
over time.

Another problem with the previous approach was that it was only
possible to override the timestamp format to one of a limited
set of timestamp formats.  There was no way out if a file to be
analysed had a timestamp that was sane yet not in the supported
set.  This is now changed to allow any timestamp format that can
be parsed by a combination of these Java date/time formats:
yy, yyyy, M, MM, MMM, MMMM, d, dd, EEE, EEEE, H, HH, h, mm, ss,
a, XX, XXX, zzz
Additionally S letter groups (fractional seconds) are supported
providing they occur after ss and separated from the ss by a dot,
comma or colon.  Spacing and punctuation is also permitted with
the exception of the question mark, newline and carriage return
characters, together with literal text enclosed in single quotes.

The full list of changes/improvements in this refactor is:

- Make TimestampFormatFinder an instantiable class
- Overrides must be specified in Java date/time format - Joda
  format is no longer accepted
- Joda timestamp formats in outputs are now derived from the
  determined or overridden Java timestamp formats, not stored
  separately
- Functionality for determining the "best" timestamp format in
  a set of lines has been moved from TextLogFileStructureFinder
  to TimestampFormatFinder, taking advantage of the fact that
  TimestampFormatFinder is now an instantiable class with state
- The functionality to quickly rule out some possible Grok
  patterns when looking for timestamp formats has been changed
  from using simple regular expressions to the much faster
  approach of using the Shift-And method of sub-string search,
  but using an "alphabet" consisting of just 1 (representing any
  digit) and 0 (representing non-digits)
- Timestamp format overrides are now much more flexible
- Timestamp format overrides that do not correspond to a built-in
  Grok pattern are mapped to a %{CUSTOM_TIMESTAMP} Grok pattern
  whose definition is included within the date processor in the
  ingest pipeline
- Grok patterns that correspond to multiple Java date/time
  patterns are now handled better - the Grok pattern is accepted
  as matching broadly, and the required set of Java date/time
  patterns is built up considering all observed samples
- As a result of the more flexible acceptance of Grok patterns,
  when looking for the "best" timestamp in a set of lines
  timestamps are considered different if they are preceded by
  a different sequence of punctuation characters (to prevent
  timestamps far into some lines being considered similar to
  timestamps near the beginning of other lines)
- Out-of-the-box Grok patterns that are considered now include
  %{DATE} and %{DATESTAMP}, which have indeterminate day/month
  ordering
- The order of day/month in formats with indeterminate day/month
  order is determined by considering all observed samples (plus
  the server locale if the observed samples still do not suggest
  an ordering)

David Turner 7abeaba8bb Prevent in-place downgrades and invalid upgrades (#41731)
Downgrading an Elasticsearch node to an earlier version is unsupported, because
we do not make any attempt to guarantee that a node can read any of the on-disk
data written by a future version. Yet today we do not actively prevent
downgrades, and sometimes users will attempt to roll back a failed upgrade with
an in-place downgrade and get into an unrecoverable state.

This change adds the current version of the node to the node metadata file, and
checks the version found in this file against the current version at startup.
If the node cannot be sure of its ability to read the on-disk data then it
refuses to start, preserving any on-disk data in its upgraded state.

This change also adds a command-line tool to overwrite the node metadata file
without performing any version checks, to unsafely bypass these checks and
recover the historical and lenient behaviour.

[7.x Backport] Force selection of calendar or fixed intervals (#41906)
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.

This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed.  And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit).  This arrangement is very
error-prone for users.

This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.

The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.

The change applies to both REST and java clients.

Update ciphers for TLSv1.3 and JDK11 if available (#42082)
This commit updates the default ciphers and TLS protocols that are used
when the runtime JDK supports them. New cipher support has been
introduced in JDK 11 and 12 along with performance fixes for AES GCM.
The ciphers are ordered with PFS ciphers being most preferred, then
AEAD ciphers, and finally those with mainstream hardware support. When
available stronger encryption is preferred for a given cipher.

This is a backport of #41385 and #41808. There are known JDK bugs with
TLSv1.3 that have been fixed in various versions. These are:

1. The JDK's bundled HttpsServer will endless loop under JDK11 and JDK
12.0 (Fixed in 12.0.1) based on the way the Apache HttpClient performs
a close (half close).
2. In all versions of JDK 11 and 12, the HttpsServer will endless loop
when certificates are not trusted or another handshake error occurs. An
email has been sent to the openjdk security-dev list and #38646 is open
to track this.
3. In JDK 11.0.2 and prior there is a race condition with session
resumption that leads to handshake errors when multiple concurrent
handshakes are going on between the same client and server. This bug
does not appear when client authentication is in use. This is
JDK-8213202, which was fixed in 11.0.3 and 12.0.
4. In JDK 11.0.2 and prior there is a bug where resumed TLS sessions do
not retain peer certificate information. This is JDK-8212885.

The way these issues are addressed is that the current java version is
checked and used to determine the supported protocols for tests that
provoke these issues.

SQL: Add initial geo support (#42031) (#42135)
Adds an initial limited implementations of geo features to SQL. This implementation is based on the [OpenGIS® Implementation Standard for Geographic information - Simple feature access](http://www.opengeospatial.org/standards/sfs), which is the current standard for GIS system implementation. This effort is concentrate on SQL option AKA ISO 19125-2. 

Queries that are supported as a result of this initial implementation

Metadata commands

- `DESCRIBE table`  - returns the correct column types `GEOMETRY` for geo shapes and geo points.
- `SHOW FUNCTIONS` - returns a list that includes supported `ST_` functions
- `SYS TYPES` and `SYS COLUMNS` display correct types `GEO_SHAPE` and `GEO_POINT` for geo shapes and geo points accordingly. 

Returning geoshapes and geopoints from elasticsearch

- `SELECT geom FROM table` - returns the geoshapes and geo_points as libs/geo objects in JDBC or as WKT strings in console.
- `SELECT ST_AsWKT(geom) FROM table;` and `SELECT ST_AsText(geom) FROM table;`- returns the geoshapes ang geopoints in their WKT representation;

Using geopoints to elasticsearch

- The following functions will be supported for geopoints in queries, sorting and aggregations: `ST_GeomFromText`, `ST_X`, `ST_Y`, `ST_Z`, `ST_GeometryType`, and `ST_Distance`. In most cases when used in queries, sorting and aggregations, these function are translated into script. These functions can be used in the SELECT clause for both geopoints and geoshapes. 
- `SELECT * FROM table WHERE ST_Distance(ST_GeomFromText(POINT(1 2), point) < 10;` - returns all records for which `point` is located within 10m from the `POINT(1 2)`. In this case the WHERE clause is translated into a range query.

Limitations:

Geoshapes cannot be used in queries, sorting and aggregations as part of this initial effort. In order to fully take advantage of geoshapes we would need to have access to geoshape doc values, which is coming in #37206. `ST_Z` cannot be used on geopoints in queries, sorting and aggregations since we don't store altitude in geo_point doc values.

This commit slightly reworks the recommendations in the docs about setting the
heap size:

* the "rules of thumb" are actually instructions that should be followed

* the reason for setting `Xmx` to 50% of the heap size is more subtle than just
  leaving space for the filesystem cache

* it is normal to see Elasticsearch using more memory than `Xmx`

* replace `cutoff` and `limit` with `threshold` since all three terms are used
  interchangeably

* since we recommend setting `Xmx` equal to `Xms`, avoid talking about setting
  `Xmx` in isolation
