This one is interesting. The third party audit task runs inside the
Gradle JVM. This means that if Gradle is started on JDK 8, the third
party audit tasks will fail as a result of the changes to support
building Elasticsearch with the JDK 9 compiler. This commit reverts the
third party audit changes to support running this task when Gradle is
started with JDK 8.

This commit modifies the build to require JDK 9 for
compilation. Henceforth, we will compile with a JDK 9 compiler targeting
JDK 8 as the class file format. Optionally, RUNTIME_JAVA_HOME can be set
as the runtime JDK used for running tests. To enable this change, we
separate the meaning of the compiler Java home versus the runtime Java
home. If the runtime Java home is not set (via RUNTIME_JAVA_HOME) then
we fallback to using JAVA_HOME as the runtime Java home. This enables:
- developers only have to set one Java home (JAVA_HOME)
- developers can set an optional Java home (RUNTIME_JAVA_HOME) to test
on the minimum supported runtime
- we can test compiling with JDK 9 running on JDK 8 and compiling with
JDK 9 running on JDK 9 in CI
* Sense HA HDFS settings and remove permission restrictions during regular execution.
This PR adds integration tests for HA-Enabled HDFS deployments, both regular and secured.
The Mini HDFS fixture has been updated to optionally run in HA-Mode. A new test suite has
been added for reproducing the effects of a Namenode failing over during regular repository
usage. Going forward, the HDFS Repository will still be subject to its self imposed permission
restrictions during normal use, but will no longer restrict them when running against an HA
enabled HDFS cluster. Instead, the plugin will rely on the provided security policy and not
further restrict the permissions so that the transparent operation to failover to a different
Namenode in the client does not raise security exceptions. Additionally, we are now testing the
secure mode with SASL based wire encryption of data between Elasticsearch and HDFS. This
includes a missing library (commons codec) in order to support this change.
Gradle 5.0 will remove support for colons in configuration and task
names. This commit fixes this for our build by removing all current uses
of colons in configuration and task names.

This commit adds the Log4j to SLF4J binding JAR to the repository-hdfs
plugin so that SLF4J can detect Log4j at runtime and therefore use the
server Log4j implementation for logging (and the usual Elasticsearch
APIs can be used for setting logging levels).

With Gradle 4.1 and newer JDK versions, we can finally invoke Gradle directly using a JDK9 JAVA_HOME without requiring a JDK8 to "bootstrap" the build. As the thirdPartyAudit task runs within the JVM that Gradle runs in, it needs to be adapted now to be JDK9 aware.
This commit also changes the `JavaCompile` tasks to only fork if necessary (i.e. when Gradle's JVM and JAVA_HOME's JVM differ).
Hadoop 2.7.x libraries fail when running on JDK9 due to the version string changing to a single
character. On Hadoop 2.8, this is no longer a problem, and it is unclear on whether the fix will be
backported to the 2.7 branch. This commit upgrades our dependency of Hadoop for the HDFS
Repository to 2.8.1.
The secure repository-hdfs tests fail on JDK 9 because some Hadoop code
reaches into sun.security.krb5. This commit adds the necessary flags to
open the java.security.jgss module. Note that these flags are actually
needed at runtime as well when using secure repository-hdfs. For now we
will punt on how best to help users obtain this when running on JDK 9
with this plugin.

We're using Vagrant in more places now than before. This commit includes a plugin that verifies
the Vagrant and Virtualbox installations for projects that depend on them. This shared code
should fix up the errors we've seen from CI builds relating to the new Kerberos fixture.
This commit fixes the error message to escape the dollar sign for
referencing a literal `$HADOOP_HOME`, which caused an error while trying
to generate an error.
closes#24878
This PR introduces a subproject in test/fixtures that contains a Vagrantfile used for standing up a
KRB5 KDC (Kerberos). The PR also includes helper scripts for provisioning principals, a few
changes to the HDFS Fixture to allow it to interface with the KDC, as well as a new suite of
integration tests for the HDFS Repository plugin.
The HDFS Repository plugin senses if the local environment can support the HDFS Fixture
(Windows is generally a restricted environment). If it can use the regular fixture, it then tests if
Vagrant is installed with a compatible version to determine if the secure test fixtures should be
enabled. If the secure tests are enabled, then we create a Kerberos KDC fixture, tasks for adding
the required principals, and an HDFS fixture configured for security. A new integration test task is
also configured to use the KDC and secure HDFS fixture and to run a testing suite that uses
authentication. At the end of the secure integration test the fixtures are torn down.
After splitting integ tests into cluster configuration and the test
runner task, we still have dependencies of the test runner added as deps
of the cluster. This commit adds dependencies directly to the cluster,
so that the runner can have other dependencies independent of what is
needed for the cluster.
This commit sets the version on the repository-hdfs Guava dependency to
version 11.0.2. This change is made to align the version here with the
version that is defined in the POM for Hadoop 2.7.1, the version of
Hadoop that the repository-hdfs plugin is based on. See HADOOP-10101 and
HADOOP-11319 for the ridiculous history of trying to upgrade Guava past
this version in the Hadoop project.

The test setup for hdfs is a little complicated for windows, needing to
check if the hdfs fixture can be run at all. This was unfortunately not
updated when the integ tests were reorganized into separate runner and
cluster setups.
This changes build files so that building Elasticsearch works with both Gradle 2.13 as well as higher versions of Gradle (tested 2.14 and 3.3), enabling a smooth transition from Gradle 2.13 to 3.x.

This commit renames the Netty 3 transport module from transport-netty to
transport-netty3. This is to make room for a Netty 4 transport module,
transport-netty4.

Removes all our logger wrappers except the wrapper for log4j1.2. If you
depend on Elasticsearch's jar in your application you'll need to declare
log4j 1.2 and/or some bridge to your favorite logger.
We did this to simplify our builds and code. No more commons-logging like
log implementation sniffing. No more optional dependency hacks in gradle.
We might one day want to use j.u.l instead of log4j. If we do want that
we can recover its wrapper by studying this commit. We didn't go directly
to j.u.l in this commit because that is a bigger change. Our logging
configuration is based on log4j1.2 and people are used to it. So it'd
be a much more fraught breaking change to do that conversion.
This fixes the `lenient` parameter to be `missingClasses`. I will remove this boolean and we can handle them via the normal whitelist.
It also adds a check for sheisty classes (jar hell with the jdk).
This is inspired by the lucene "sheisty" classes check, but it has false positives. This check is more evil, it validates every class file against the extension classloader as a resource, to see if it exists there. If so: jar hell.
This jar hell is a problem for several reasons:
1. causes insanely-hard-to-debug problems (like bugs in forbidden-apis)
2. hides problems (like internal api access)
3. the code you think is executing, is not really executing
4. security permissions are not what you think they are
5. brings in unnecessary dependencies
6. its jar hell
The more difficult problems are stuff like jython, where these classes are simply 'uberjared' directly in, so you cant just fix them by removing a bogus dependency. And there is a legit reason for them to do that, they want to support java 1.4.
Migrated from ES-Hadoop. Contains several improvements regarding:
* Security
Takes advantage of the pluggable security in ES 2.2 and uses that in order
to grant the necessary permissions to the Hadoop libs. It relies on a
dedicated DomainCombiner to grant permissions only when needed only to the
libraries installed in the plugin folder
Add security checks for SpecialPermission/scripting and provides out of
the box permissions for the latest Hadoop 1.x (1.2.1) and 2.x (2.7.1)
* Testing
Uses a customized Local FS to perform actual integration testing of the
Hadoop stack (and thus to make sure the proper permissions and ACC blocks
are in place) however without requiring extra permissions for testing.
If needed, a MiniDFS cluster is provided (though it requires extra
permissions to bind ports)
Provides a RestIT test
* Build system
Picks the build system used in ES (still Gradle)
