* Revert "make sure CliCoordinator initializes and starts DerbyMetadataStorage first if configured"
This reverts commit 54f5644054626d4a9e2448bb4bd5e6ce9a9fca1d.
* make sure CliCoordinator initializes and starts DerbyMetadataStorage first if configured
* Normalized Cost Balancer
* Adding documentation and renaming to use diskNormalizedCostBalancer
* Remove balancer from the strings
* Update docs and include random cost balancer
* Fix checkstyle issues
* support finding segments from a AWS S3 storage.
* add more Uts
* address comments and add a document for the feature.
* update docs indentation
* update docs indentation
* address comments.
1. add a Ut for json ser/deser for the config object.
2. more informant error message in a Ut.
* address comments.
1. use @Min to validate the configuration object
2. change updateDescriptor to a string as it does not take an argument otherwise
* fix a Ut failure - delete a Ut for testing default max length.
* Show candidate hosts for the given query
* Added test cases & minor changes to address comments
* Changed path-param to query-pram for intervals/numCandidates
1) Modify CliHadoopIndexer to share constant from `TaskConfig.DEFAULT_DEFAULT_HADOOP_COORDINATES`
2) add comment to pom.xml as discussed in
https://github.com/druid-io/druid/pull/3044
fix name
All query metrics now start with toolChest.makeMetricBuilder, and all of
*those* now start with DruidMetrics.makePartialQueryTimeMetric. Also, "id"
moved to common code, since all query metrics added it anyway.
In particular this will add query-type specific dimensions like "threshold"
and "numDimensions" to servlet-originated metrics like query/time.
* Datasource as lookup tier
* Adds an option to let indexing service tasks pull their lookup tier from the datasource they are working for.
* Fix bad docs for lookups lookupTier
* Add Datasource name holder
* Move task and datasource to be pulled from Task file
* Make LookupModule pull from bound dataSource
* Fix test
* Fix code style on imports
* Fix formatting
* Make naming better
* Address code comments about naming
Fixes#2682
IndexingService helpers are added according to the settings in runtime.properties.
Rather than having all the config.isXXX checks there, it makes sense to have a pluggable
approach for allowing the dynamic configuration to bring in implementations for helpers
without having to have hard-coded sets of available helpers. Plus, it will also make it possible for extensions to plug helpers in.
With https://github.com/druid-io/druid-api/pull/76, we could conditionally bind a helper to Coordinator's runlist.
The condition is driven by the value set in the runtime.properties.
Geared towards supporting transactional inserts of new segments. This involves an
interface "DataSourceMetadata" that allows combining of partially specified metadata
(useful for partitioned ingestion).
DataSource metadata is stored in a new "dataSource" table.
* Eliminate exclusion groups from pull-deps
* Only consider dependency nodes in pull-deps if they are not in the following scopes
* provided
* test
* system
* Fix a bunch of `<scope>provided</scope>` missing tags
* Better exclusions for a couple of problematic libs

1. The thread "qtp925672150-62" holds the lock on InternalInjectorCreator.class,
used by Scopes.SINGLETON, and wants the lock on "handlers" in Lifecycle.addMaybeStartHandler
called by DiscoveryModule.getServiceAnnouncer.
2. The main thread holds the lock on "handlers" in Lifecycle.addMaybeStartHandler, which it
took because it's trying to add the ExecutorLifecycle to the lifecycle. main is trying
to get the InternalInjectorCreator.class lock because it's running ExecutorLifecycle.start,
which does some Jackson deserialization, and Jackson needs that lock in order to inject
stuff into the Task it's deserializing.
This patch eagerly instantiates ChatHandlerResource (which I believe is what's trying to
create the ServiceAnnouncer in the qtp925672150-62 jetty thread) and the ExecutorLifecycle.
* Moves last run task state information to Worker
* Makes WorkerTaskRunner a TaskRunner which has interfaces to help with getting information about a Worker
- Add druid.indexer.server.maxChatRequests, which sets up a QoSFilter on the main Jetty server.
- Deprecate druid.indexer.runner.separateIngestionEndpoint
- Deprecate druid.indexer.server.chathandler.*
* Don't put druid****selfcontained.jar at the end of the hadoop isolated classpath
* Add `<scope>provided</scope>` to prevent repeated dependency inclusion in the extension directories
