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
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.
I've noticed throughout the code that we have a need to remove the boilerplate lifecycle check when starting/rescheduling certain runnables. This provides a simpler implementation to get this functionality without duplicating it.
The `ingest_took` is separate from `took`, which keeps track how much time is spent on indexing/deleting/updating.
The `ingest_took` is only visible in the rest response if at least for one bulk item has ingest enabled.
In case where the publish address is different to all bound addresses and an explicit publish_port
setting is not provided, the publish_port is now selected as the unique port of bound addresses.
An exception is thrown in case of ambiguities.
Closes#16626
If a node was isolated from the cluster while a delete was happening,
the node will ignore the deleted operation when rejoining as we couldn't
detect whether the new master genuinely deleted the indices or it is a
new fresh "reset" master that was started without the old data folder.
We can now be smarter and detect these reset masters and actually delete
the indices on the node if its not the case of a reset master.
Note that this new protection doesn't hold if the node was shut down. In
that case it's indices will still be imported as dangling indices.
Closes#16825Closes#11665
If you connect to a client node and call _cat/nodes, and there is at least another client node in the cluster, the http address cannot be retrieved thus we get an NPE. This commit prevents an NPE from being thrown. This bug was introduced with #16770
