This commit removes the ability to use string fields on indices created on or
after 5.0. Dynamic mappings now generate text fields by default for strings
but there are plans to also add a sub keyword field (in a future PR).
Most of the changes in this commit are just about replacing string with
keyword or text. Some tests have been removed because they existed because of
corner cases of string mappings like setting ignore-above on a text field or
enabling term vectors on a keyword field which are now impossible.
The plan is to remove strings entirely in 6.0.
This method was originally introduced to prevent client nodes from connecting to other client nodes directly in the cluster. That said, it worked only if node.client was set to true and not when node.master and node.data were both set to false. It looks safe to remove, which allows to solve all kinds of problems around monitoring that happen wherever there are 2 or more clients nodes in the cluster, and a REST call hits one of them (node counts are off, clients nodes are missing).
Recent simplifications to org.elasticsearch.Version led to "-SNAPSHOT"
to not be displayed in the node version upon startup. Yet, this is
useful information to have. This simple commit adds back the display of
"-SNAPSHOT" in the version on startup if the build is a snapshot build.
Closes#16908
This commit refactors the bootstrap checks into a dedicated class. The
refactoring provides a model for different limits per operating system,
and provides a model for unit tests for individual checks.
Closes#16844
This is a backport of #16845 in this branch.
We now also support marking settings with `SettingsProperty.Deprecated`.
If the setting is still used, it will print a `warn` to the user.
In this case we compute elapsed time and `System.nanoTime()` is designed to do just do that.
The absolute timing `System.currentTimeMillis()` provides in not needed and the relative timing `System.nanoTime()` provides is likely to be more accurate.
Use 'includeSegmentFileSizes' as the flag name to report disk usage.
Added test that verifies reported segment disk usage is growing accordingly after adding a document.
Documentation: Reference the new parameter as part of indices stats.
In 2.2, the client nodes created internally by a tribe node were changed
to be explicit about which settings the client nodes use, no longer
loading all settings from elasticsearch.yml. However, some settings were
missed, notably network bind settings. This change adds those settings
to be passed through, as well as adds unit tests for building the tribe
client node settings.
