This commit ensures that the data, logs, and config directories have the
proper ownership after the packages are installed. Additionally, this
commit ensures that the configs in /etc/elasticsearch are preserved
after removal of the RPM package.
If a Writeable.Reader returns null it is always a bug, probably one that
will cause corruption in the StreamInput it was trying to read from. This
commit adds a check that attempts to catch these errors quickly including
the name of the reader.
We currently have a `discovery.zen.master_election.filter_client` setting that control whether their ping responses are ignored for master election (which is the current default). With the push to treat client nodes as normal nodes (and promote the transport/rest clients for client work), this should be changed. This commit remove this setting and it's companion `discovery.zen.master_election.filter_data` setting (currently defaulting to false) in favor of singe `discovery.zen.master_election.ignore_non_master_pings` setting with more intuitive name (defaulting to false).

readFrom is confusing because it requires an instance of the type that it
is reading but it doesn't modify it. But we also have (deprecated) methods
named readFrom that *do* modify the instance. The "right" way to implement
the non-modifying readFrom is to delegate to a constructor that takes a
StreamInput so that the read object can be immutable. Now that we have
`@FunctionalInterface`s it is fairly easy to register things by referring
directly to the constructor.
This change modifying NamedWriteableRegistry so that it does that. It keeps
supporting `registerPrototype` which registers objects to be read by
readFrom but deprecates it and delegates it to a new `register` method
that allows passing a simple functional interface. It also cuts Task.Status
subclasses over to using that method.
The start of #17085
The available memory metric was always set to `0` since 2.0.beta1 (bug). was left behind but never set. Turns out the section wasn't that useful, as it would only output the total memory available throughout all nodes in the cluster. We decided to remove the section then.
This commit fixes a line-length checkstyle violation in
YamlSettingsLoaderTests.java and removes this file from the checkstyle
line-length suppressions.
This commit fixes a line-length checkstyle violation in
JsonSettingsLoaderTests.java and removes this file from the checkstyle
line-length suppressions.
The test was checking that we'd set the headers properly but in some cases
the request had yet to come in because it was running on another thread.
Now we wait for the headers to show up before failing the test.
Closes#17299
This commit adds a test that NoDuplicatesProperties throws a
NullPointerException if an attempt is made to put a key that corresponds
to a null value. This behavior ultimately comes from the super class
Properties but the test ensures that we retain this behavior.
This commit fixes a line-length checkstyle violation in
PropertiesSettingsLoader.java and removes this file from the checkstyle
line-length suppressions.
Debian asks during installation, if the configuration file should be updated.
This is asked via a prompt and thus hangs.
This adds an option to always update to the newer config file, so automated
installation keeps working.
The sole constructor of XContentSettingsLoader accepts a boolean flag
that indicates whether or not null values parsed from the source should
be rejected or not. Previously a true value for this flag meant that
null values should be rejected. With this commit, the meaning of this
flag is reversed so that a true value means that null values should be
accepted (note that this is needed due to the way that settings are
unset via the cluster update settings API). The name of this flag has
been changed from guardAgainstNullValuedSettings to allowNullValues, for
clarity.
All our fields are supposed to support multi fields, so we could put the logic in
`TypeParsers.parseField` instead of duplicating the logic in every type parser.
Change version, required a minor fix in the RPM building.
In case of a alpha/beta version, the release will contain alpha/beta
as the RPM version cannot contains dashes/tildes.
Waiting for completion of list tasks tasks can cause an infinite loop of a list tasks task waiting for its own completion or completion of its children. To reproduce run:
```
curl "localhost:9200/_tasks?wait_for_completion"
```
This commit adds a guard against null-valued settings that are loaded
from yaml or json settings files, and also adds a test that ensures
the same remains true for settings loaded from properties files.
