Apache Druid web console
This is the unified Druid web console that servers as a data management layer for Druid.
How to watch and run for development
- You need to be within the
web-consoledirectory - Install the modules with
npm install - Run
npm run compileto compile the scss files - Run
npm startwill start in development mode and will proxy druid requests tolocalhost:8888
Note: you can provide an environment variable to proxy to a different Druid host like so: druid_host=1.2.3.4:8888 npm start
Note: you can provide an environment variable use webpack-bundle-analyzer as a plugin in the build script or like so: BUNDLE_ANALYZER_PLUGIN='TRUE' npm start
To try the console in (say) coordinator mode you could run it as such:
druid_host=localhost:8081 npm start
Description of the directory structure
A lot of the directory structure was created to preserve the existing console structure as much as possible.
As part of this repo:
assets/- The images (and other assets) used within the consolee2e-tests/- End-to-end tests for the consolelib/- A place where some overrides to the react-table stylus files live, this is outside of the normal SCSS build system.public/- The compiled destination of the file powering this consolescript/- Some helper bash scripts for running this consolesrc/- This directory (together withlib) constitutes all the source code for this console

Updating the list of license files
From the web-console directory run script/licenses
Running End-to-End Tests
From the web-console directory:
- Build druid distribution:
script/druid build - Start druid cluster:
script/druid start - Run end-to-end tests:
npm run test-e2e - Stop druid cluster:
script/druid stop
If you already have a druid cluster running on the standard ports, the steps to build/start/stop a druid cluster can be skipped.
Debugging
Screenshots
e2e-tests/util/debug.ts:saveScreenshotIfError() is used to save a screenshot of the web console
when the test fails. For example, if e2e-tests/tutorial-batch.spec.ts fails, it will create
load-data-from-local-disk-error-screenshot.png.
Disabling Headless Mode
Disabling headless mode while running the tests can be helpful. This can be done via the DRUID_E2E_TEST_HEADLESS
environment variable, which defaults to true.
Running Against Alternate Web Console
The environment variable DRUID_E2E_TEST_UNIFIED_CONSOLE_PORT can be used to target a web console running on a
non-default port (i.e., not port 8888). For example, this environment variable can be used to target the
development mode of the web console (started via npm start), which runs on port 18081.
