Reorganize Travis CI jobs into smaller faster (and more) jobs. Add
various maven options to skip unnecessary work and refactored Travis CI
job definitions to follow DRY.
Detailed changes:
.travis.yml
- Refactor build logic to get rid of copy-and-paste logic
- Skip static checks and enable parallelism for maven install
- Split static analysis into different jobs to ease triage
- Use "name" attribute instead of NAME environment variable
- Split "indexing" and "web console" out of "other modules test"
- Split 2 integration test jobs into multiple smaller jobs
build.sh
- Enable parallelism
- Disable more static checks
travis_script_integration.sh
travis_script_integration_part2.sh
integration-tests/README.md
- Use TestNG groups instead of shell scripts and move definition of jobs
into Travis CI yaml
integration-tests/pom.xml
- Show elapsed time of individual tests to aid in future rebalancing of
Travis CI integration test jobs run time
TestNGGroup.java
- Use TestNG groups to make it easy to have multiple Travis CI
integration test jobs. TestNG groups also make it easier to have an
"other" integration test group and make it less likely a test will
accidentally not be included in a CI job.
IT*Test.java
AbstractITBatchIndexTest.java
AbstractKafkaIndexerTest.java
- Add TestNG group
- Fix various IntelliJ inspection warnings
- Reduce scope of helper methods since the TestNG group annotation on
the class makes TestNG consider all public methods as test methods
pom.xml
- Allow enforce plugin to be run from command-line
- Bump resources plugin version so that "[debug] execute contextualize"
output is correctly suppressed by "mvn -q"
- Bump exec plugin version so that skip property is renamed from "skip"
to "exec.skip"
web-console/pom.xml
- Add property to allow disabling javascript-related work. This property
is overridden in Travis CI to speed up the jobs.
* Fix dependency analyze warnings
Update the maven dependency plugin to the latest version and fix all
warnings for unused declared and used undeclared dependencies in the
compile scope. Added new travis job to add the check to CI. Also fixed
some source code files to use the correct packages for their imports.
* Fix licenses and dependencies
* Fix licenses and dependencies again
* Fix integration test dependency
* Address review comments
* Fix unit test dependencies
* Fix integration test dependency
* Fix integration test dependency again
* Fix integration test dependency third time
* Fix integration test dependency fourth time
* Fix compile error

* Upgrade various build and doc links to https.
Where it wasn't possible to upgrade build-time dependencies to https,
I kept http in place but used hardcoded checksums or GPG keys to ensure
that artifacts fetched over http are verified properly.
* Switch to https://apache.org.
* update sys.servers table to show all servers
* update docs
* Fix integration test
* modify test query for batch integration test
* fix case in test queries
* make the server_type lowercase
* Apply suggestions from code review
Co-Authored-By: Himanshu <g.himanshu@gmail.com>
* Fix compilation from git suggestion
* fix unit test
* Bump Checkstyle to 8.20
Moderate severity vulnerability that affects:
com.puppycrawl.tools:checkstyle
Checkstyle prior to 8.18 loads external DTDs by default,
which can potentially lead to denial of service attacks
or the leaking of confidential information.
Affected versions: < 8.18

- Require 'intervals' in WindowedSegmentId (since it won't be written by hand)

* Throwable is kept before firing a Runtime Exception.
* Fix unused assignments.
* integration-tests: make ITParallelIndexTest still work in parallel
Follow-up to #7181, which made the default behavior for index_parallel tasks
non-parallel.
* Validate that parallel index subtasks were run
Previously, the test validated that the data source that we ingested from still
had the same query responses that it did before the second ingestion. This is
less useful than validating queries against the newly created data source.
The new queries file differs from the old one in that its maxTime is earlier due
to the interval selected by the reindex, and in that it does not query for the
dropped metric "count".
* index_parallel: support !appendToExisting with no explicit intervals
This enables ParallelIndexSupervisorTask to dynamically request locks at runtime
if it is run without explicit intervals in the granularity spec and with
appendToExisting set to false. Previously, it behaved as if appendToExisting
was set to true, which was undocumented and inconsistent with IndexTask and
Hadoop indexing.
Also, when ParallelIndexSupervisorTask allocates segments in the explicit
interval case, fail if its locks on the interval have been revoked.
Also make a few other additions/clarifications to native ingestion docs.
Fixes#6989.

PR description on GitHub updated to match.

This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR.
Some of the changes:
- Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names.
- Generified `ComplexMetricExtractor`
* Replace statusCode with status (#6333)
Also changed runnerStatusCode to runnerStatus to keep things consistent
* Add unit test
* Add status param to TaskStatusPlus
Revert to statusCode and runnerStatusCode
* Add additional status member to TaskStatusPlus
* Change TaskResponseObject to match overlord's response object
* Address PR comments
* address comments
* Add runtime exception after logging error
* Remove (deprecated)status member variable from TaskStatusPlus
* Minor change
* ITTLSTest: Retry on "Connection reset by peer".
This sometimes happens and causes tests to fail spuriously.
* Better error messages when retries are exhausted.
* Adding licenses and enable apache-rat-plugi.

* ParseSpec: Remove default setting.
Having a default ParseSpec implementation is bad for users, because it masks
problems specifying the format. Two common problems masked by this are specifying
the "format" at the wrong level of the JSON, and specifying a format that
Druid doesn't support. In both cases, having a default implementation means that
users will get the delimited parser rather than an error, and then be confused
when, later on, their data failed to parse.

* [Integration-tests] Allow specifying additional properties while connecting to kafka
Use Case - For running integration tests with a secure kafka cluster we
need to set additional properties.
This PR adds a way to pass in additional properties to kafka
consumer/producer used in kafka integration tests.
Additionally it also adds a flag to skip creating/deleting kafka topic
from tests since not all secure kafka clusters allow all users to
manage topics.

* Change to handle all negatives
Noticed this in our internal testing, sometimes realtime index tasks in
kafkaIndexing service can get stuck waiting for handoff if datasource
is disabled before there task completion.
This is a workaround to ensure integration tests do not hit this case
until https://github.com/druid-io/druid/issues/1729 is fixed.
Excludes tests from AvoidStaticImport, since those are used often there and
I didn't want to make this changeset too large. Production code use was minimal
and I switched those to non-static imports.
* Add configs to enable running integration tests for cluster running behind proxy
As part of https://issues.apache.org/jira/browse/KNOX-758
I am working on adding support for proxying druid queries & UIs using
Apache KNOX gateway.
This PR adds support for integration-tests to be run using the proxy
gateway.
Changes Include -
1) Instead of hostName and port, ability to specify url in the config
file.
2) tests now use HTTPClient defined in DruidTestModule that can pass in
the request.
Note - the config changes are backwards compatible and existing configs
should work fine.
