Jason Tedor bb66f3b76b Explicitly reject duplicate data paths
Duplicate data paths already fail to work because we would attempt to
take out a node lock on the directory a second time which will fail
after the first lock attempt succeeds. However, how this failure
manifests is not apparent at all and is quite difficult to
debug. Instead, we should explicitly reject duplicate data paths to make
the failure cause more obvious.

Jason Tedor 5108fa7529 Remove unneeded weak reference from prefix logger
We have a custom logger implementation known as a prefix logger that is
used to write every message by the logger with a given prefix. This is
useful for node-level, index-level, and shard-level messages where we
want to log the node name, index name, and shard ID, respectively, if
possible. The mechanism that we employ is that of a marker. Log4j has a
built-in facility for managing these markers, but its effectively a
memory leak because these markers are held in a map and can never be
released. This is problematic for us since indices and shards do not
necessarily have infinite life spans and so on a node where there are
many indices being creted and destroyed, this infinite lifespan can be a
problem indeed. To solve this, we use our own cache of markers. This is
necessary to prevent too many instances of the marker for the same
prefix from being created (just think of all the shard-level components
that exist in the system), and to workaround the effective leak in
Log4j. These markers are stored as weak references in a weak hash
map. It is these weak references that are unneeded. When a key is
removed from a weak hash map, the corresponding entry is placed on a
reference queue that is eventually cleared. This commit simplifies
prefix logger by removing this unnecessary weak reference wrapper.

Jason Tedor fc3280b3cf Expose logs base path
For certain situations, end-users need the base path for Elasticsearch
logs. Exposing this as a property is better than hard-coding the path
into the logging configuration file as otherwise the logging
configuration file could easily diverge from the Elasticsearch
configuration file. Additionally, Elasticsearch will only have
permissions to write to the log directory configured in the
Elasticsearch configuration file. This commit adds a property that
exposes this base path.

One use-case for this is configuring a rollover strategy to retain logs
for a certain period of time. As such, we add an example of this to the
documentation.

Additionally, we expose the property es.logs.cluster_name as this is
used as the name of the log files in the default configuration.

Finally, we expose es.logs.node_name in cases where node.name is
explicitly set in case users want to include the node name as part of
the name of the log files.

Ryan Ernst fb690ef748 Settings: Add infrastructure for elasticsearch keystore
This change is the first towards providing the ability to store
sensitive settings in elasticsearch. It adds the
`elasticsearch-keystore` tool, which allows managing a java keystore.
The keystore is loaded upon node startup in Elasticsearch, and used by
the Setting infrastructure when a setting is configured as secure.

There are a lot of caveats to this PR. The most important is it only
provides the tool and setting infrastructure for secure strings. It does
not yet provide for keystore passwords, keypairs, certificates, or even
convert any existing string settings to secure string settings. Those
will all come in follow up PRs. But this PR was already too big, so this
at least gets a basic version of the infrastructure in.

The two main things to look at.  The first is the `SecureSetting` class,
which extends `Setting`, but removes the assumption for the raw value of the
setting to be a string. SecureSetting provides, for now, a single
helper, `stringSetting()` to create a SecureSetting which will return a
SecureString (which is like String, but is closeable, so that the
underlying character array can be cleared). The second is the
`KeyStoreWrapper` class, which wraps the java `KeyStore` to provide a
simpler api (we do not need the entire keystore api) and also extend
the serialized format to add metadata needed for loading the keystore
with no assumptions about keystore type (so that we can change this in
the future) as well as whether the keystore has a password (so that we
can know whether prompting is necessary when we add support for keystore
passwords).

Today if an older version of a plugin exists, we fail to notify the user

verification, we attempt to read the plugin descriptors for all existing
plugins. When an older version of a plugin is sitting on disk, we will
attempt to read this old plugin descriptor and fail due to a version
mismatch. This leads to an unhelpful error message. Instead, we should
check for existence of the plugin as part of the verification phase, but
before attempting to read plugin descriptors for existing plugins. This
enables us to provide a helpful error message to the user.

Jason Tedor f16c308efd Assert status logger does not warn on Log4j usage
Today if you start Elasticsearch with the status logger configured to
the warn level, or use a transport client with the default status logger
level, you will see warn messages about deprecation loggers being
created with different message factories and that formatting might be
broken. This happens because the deprecation logger is constructed using
the message factory from its parent, an artifact leftover from the first
Log4j 2 implementation that used a custom message factory. When that
custom message factory was removed, this constructor invocation should
have been changed to not explicitly use the message factory from the
parent. This commit fixes this invocation. However, we also had some
status checking to all tests to ensure that there are no warn status log
messages that might indicate a configuration problem with Log4j 2. These
assertions blow up badly without the fix for the deprecation logger
construction, and also caught a misconfiguration in one of the logging
tests.

Jason Tedor 875387936b Simplify Log4j shutdown hack test
The Log4j shutdown hack test tests that a hack we have in place to
workaround a bug in Log4j during shutdown is effective. Log4j can use
JMX to control logging levels, but we disable this through the use of a
system property log4j2.disable.jmx (mainly because there is no need for
this feature, but it also means granting additional security
permissions). The bug in Log4j is that during shutdown, it neglects to
check whether or not its usage of JMX is disable and so it attempts to
unregister management beans, leading to a permissions violation. The
test works by attempting to shutdown Log4j and thus triggering the bad
code path. With the Log4j hack in place, we have introduced jar hell so
that its our code running instead of code from the Log4j jar. Our code
correctly checks that the usage of JMX is disabled and thus does not
trip on a permissions violation. The test was a little complicated in
that it attempted to just grant the minimal permissions needed for Log4j
to do its thing, but this can sometimes lead to other unwanted
permissions violations because the permissions put in place are more
restrictive necessary. This commit simplifies this situation by
rewriting the test to only deny Log4j the sole permission needed to
trigger the bug.

Jason Tedor 0eff7daf5b Fix logging hierarchy configs
Today when setting the logging level via the command-line or an API
call, the expectation is that the logging level should trickle down the
hiearchy to descendant loggers. However, this is not necessarily the
case. For example, if loggers x and x.y are already configured then
setting the logging level on x will not descend to x.y. This is because
the logging config for x.y has already been forked from the logging
config for x. Therefore, we must explicitly descend the hierarchy when
setting the logging level and that is what this commit does.

Jason Tedor fbe27664a6 Fix prefix logging
Today we add a prefix when logging within Elasticsearch. This prefix
contains the node name, and index and shard-level components if
appropriate.

Due to some implementation details with Log4j 2 , this does not work for
integration tests; instead what we see is the node name for the last
node to startup. The implementation detail here is that Log4j 2 there is
only one logger for a name, message factory pair, and the key derived
from the message factory is the class name of the message factory. So,
when the last node starts up and starts setting prefixes on its message
factories, it will impact the loggers for the other nodes.

Additionally, the prefixes are lost when logging an exception. This is
due to another implementation detail in Log4j 2. Namely, since we log
exceptions using a parameterized message, Log4j 2 decides that that
means that we do not want to use the message factory that we have
provided (the prefix message factory) and so logs the exception without
the prefix.

This commit fixes both of these issues.

Tanguy Leroux 6090c51fc5 Add quiet option to disable console logging (#20422)
This commit adds a -q/--quiet option to Elasticsearch so that it does not log anything in the console and closes stdout & stderr streams. This is useful for SystemD to avoid duplicate logs in both journalctl and /var/log/elasticsearch/elasticsearch.log while still allows the JVM to print error messages in stdout/stderr if needed.

Jason Tedor d547b79224 Separate configs for logging tests
The evil logger tests rely on external configuration. This configuration
is shared between these tests which means that changing the
configuration for one test can cause an unrelated test to fail. In
particular, removing the appenders on the root logger so that inherited
loggers in one test do not have a console and file appender by default
breaks tests that were expecting the root logger to have these
appenders. This commit separates these configs so that these tests are
not subject to this problem.

Jason Tedor 55a2f26b21 Logging shutdown hack
Log4j has a bug where on shutdown it ignores that JMX might be disabled;
since it does not respect this on shutdown, it proceeds to attempt to
access JMX leading to a security exception that should have otherwise
not occurred had it respected that JMX is disabled. This commit
intentionally introduces jar hell with the Server class to work around
this bug until a fix is released.

Jason Tedor de43565abc Do not log full bootstrap checks exception
By default, when an exception causes the JVM to terminate, the stack
trace is printed. In the case of failing bootstrap checks, this stack
trace is useless to the user, and might even distract them from seeing
that the bootstrap checks failed for reasons under their control. With
this commit, we cause the stack trace for a failing bootstrap check to
be truncated.

We also modify some methods to not declare that they throw the top level
checked exception type Exception, but instead explicitly declare the
exceptions that they throw. These exceptions are caught and wrapped in a
BootstrapException so that we can percolate only two exception types out
of Bootstrap#init as checked exception, BootstrapException and
NodeValidationException.

Simon Willnauer 5616251f22 Remove `node.mode` and `node.local` settings (#19428)
Today `node.mode` and `node.local` serve almost the same purpose, they
are a shortcut for `discovery.type` and `transport.type`. If `node.local: true`
or `node.mode: local` is set elasticsearch will start in _local_ mode which means
only nodes within the same JVM are discovered and a non-network based transport
is used. The _local_ mode it only really used in tests or if nodes are embedded.
For both, embedding and tests explicit configuration via `discovery.type` and `transport.type`
should be preferred.

This change removes all the usage of these settings and by-default doesn't
configure a default transport implemenation since netty is now a module. Yet, to make
the user expericence flawless, plugins or modules can set a `http.type.default` and
`transport.type.default`. Plugins set this via `PluginService#additionalSettings()`
which enforces _set-once_ which prevents node startup if set multiple times. This means
that our distributions will just startup with netty transport since it's packaged as a
module unless `transport.type` or `http.transport.type` is explicitly set.

This change also found a bunch of bugs since several NamedWriteables were not registered if a
transport client is used. Now that we don't rely on the `node.mode` leniency which is inherited
instead of using explicit settings, `TransportClient` uses `AssertingLocalTransport` which detects these problems since it serializes all messages.

Jason Tedor f9d55be1ed Rename UserError
The top-level class Throwable represents all errors and exceptions in
Java. This hierarchy is divided into Error and Exception, the former
being serious problems that applications should not try to catch and the
latter representing exceptional conditions that an application might
want to catch and handle. This commit renames
org.elasticsearch.cli.UserError to org.elasticsearch.UserException to
make its name consistent with where it falls in this hierarchy.

Boaz Leskes 6861d3571e Persistent Node Ids (#19140)
Node IDs are currently randomly generated during node startup. That means they change every time the node is restarted. While this doesn't matter for ES proper, it makes it hard for external services to track nodes. Another, more minor, side effect is that indexing the output of, say, the node stats API results in creating new fields due to node ID being used as keys.

The first approach I considered was to use the node's published address as the base for the id. We already [treat nodes with the same address as the same](https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/discovery/zen/NodeJoinController.java#L387) so this is a simple change (see [here](https://github.com/elastic/elasticsearch/compare/master...bleskes:node_persistent_id_based_on_address)). While this is simple and it works for probably most cases, it is not perfect. For example, if after a node restart, the node is not able to bind to the same port (because it's not yet freed by the OS), it will cause the node to still change identity. Also in environments where the host IP can change due to a host restart, identity will not be the same. 

Due to those limitation, I opted to go with a different approach where the node id will be persisted in the node's data folder. This has the upside of connecting the id to the nodes data. It also means that the host can be adapted in any way (replace network cards, attach storage to a new VM). I

It does however also have downsides - we now run the risk of two nodes having the same id, if someone copies clones a data folder from one node to another. To mitigate this I changed the semantics of the protection against multiple nodes with the same address to be stricter - it will now reject the incoming join if a node exists with the same id but a different address. Note that if the existing node doesn't respond to pings (i.e., it's not alive) it will be removed and the new node will be accepted when it tries another join.

Last, and most importantly, this change requires that *all* nodes persist data to disk. This is a change from current behavior where only data & master nodes store local files. This is the main reason for marking this PR as breaking.

Other less important notes:
- DummyTransportAddress is removed as we need a unique network address per node. Use `LocalTransportAddress.buildUnique()` instead.
- I renamed `node.add_lid_to_custom_path` to `node.add_lock_id_to_custom_path` to avoid confusion with the node ID which is now part of the `NodeEnvironment` logic.
- I removed the `version` paramater from `MetaDataStateFormat#write` , it wasn't really used and was just in the way :)
- TribeNodes are special in the sense that they do start multiple sub-nodes (previously known as client nodes). Those sub-nodes do not store local files but derive their ID from the parent node id, so they are generated consistently.

Jason Tedor 3343ceeae4 Do not catch throwable
Today throughout the codebase, catch throwable is used with reckless
abandon. This is dangerous because the throwable could be a fatal
virtual machine error resulting from an internal error in the JVM, or an
out of memory error or a stack overflow error that leaves the virtual
machine in an unstable and unpredictable state. This commit removes
catch throwable from the codebase and removes the temptation to use it
by modifying listener APIs to receive instances of Exception instead of
the top-level Throwable.

Ryan Ernst 454de6a8f2 Tests: Remove unnecessary evil jarhell tests
We have 3 evil tests for jarhell. They have been failing in java 9
because of how evil they are. The first checks the leniency we add for
jarhell in the jdk itself. This is unecessary, since if the leniency
wasn't there, we would already be failing all jarhell checks. The second
is checking the compile version is compatible with the jdk. This is
simpler since we don't need to fake the java version: we know 1.7 should
be compatibile with both java 8 and 9, so we can use that as a constant.
Finally the last test checks if the java version system property is
broken. This is simply something we should not check, we have to trust
that java specifies it correctly, and again, if it was broken, all
jarhell checks would be broken.
