* Make AutoScaler, ProvisioningStrategy and BaseWorkerBehaviorConfig extension points; More logging in PendingTaskBasedWorkerProvisioningStrategy
* Address comments and fix a bug
* Extract method
* debug logging
* Rename BaseWorkerBehaviorConfig to WorkerBehaviorConfig and WorkerBehaviorConfig to DefaultWorkerBehaviorConfig
* Fixes
* Priority on loading for primary replica
* Simplicity fixes
* Fix on skipping drop for quick return.
* change to debug logging for no replicants.
* Fix on filter logic
* swapping if-else
* Fix on wrong "hasTier" logic
* Refactoring of LoadRule
* Rename createPredicate to createLoadQueueSizeLimitingPredicate
* Rename getHolderList to getFilteredHolders
* remove varargs
* extract out currentReplicantsInTier
* rename holders to holdersInTier
* don't do temporary removal of tier.
* rename primaryTier to tierToSkip
* change LinkedList to ArrayList
* Change MinMaxPriorityQueue in DruidCluster to TreeSet.
* Adding some comments.
* Modify log messages in light of predicates.
* Add in-method comments
* Don't create new Object2IntOpenHashMap for each run() call.
* Cache result from strategy call in the primary assignment to be reused during the same run.
* Spelling mistake
* Cleaning up javadoc.
* refactor out loading in progress check.
* Removed redundant comment.
* Removed forbidden API
* Correct non-forbidden API.
* Precision in variable type for NavigableSet.
* Obsolete comment.
* Clarity in method call and moving retrieval of ServerHolder into method call.
* Comment on mutability of CoordinatoorStats.
* Added auxiliary fixture for dropping.
* Add identity to query metrics, logs.
Also fix a bug where unauthorized requests would not emit any logs or metrics,
and instead would log a "Tried to emit logs and metrics twice" warning.
Also rename QueryResource's "getServer" to "cancelQuery", because that's what
it does.
* Do not emit identity by default.
* SQL: Delay query translation until the end of planning.
This fixes a bug in which input rels to nested queries could get swapped
out by the optimizer, leading to incorrect nested query planning.
This also, I hope, makes the query translation code easier to understand. At
least for me, the PartialDruidQuery -> DruidQuery -> Query chain is easier
to understand than the previous-existing rule spaghetti.
* Make test more consistent.
* Fix test.
* remove ServerConfig from DruidNode as all information needs to be present in DruidNode serialized form
* sanitize output of /druid/coordinator/v1/cluster endpoint
* Added org.joda.time.DateTime#(java.lang.String) to forbidden API.
* Added org.joda.time.DateTime#(java.lang.String, org.joda.time.format.DateTimeFormatter) to forbidden API.
* Add additional APIs that may create DateTime with default time zone
* Add helper function that accepts formatter to parse String.
* Add additional forbidden APIs
* Replace existing usage of forbidden APIs
* Use wrapper class to enforce Chronology on DateTimeFormatter.
* Creates constant UtcFormatter for constant ISODateTimeFormat.
* Add flattenSpec support to the Avro parser.
Also:
- Refactor the JSONPathParser a bit so it can share flattening code
with Avro (see ObjectFlatteners).
- Remove the JSONParser. It was only used in two places: by
UriNamespaceExtractor, and as a base for JSONToLowerParser. Migrated
the former to JSONPathParser and made the latter a standalone.
- Move GenericRecordAsMap to the Parquet extension, since the Avro
extension no longer uses it.
* Fix indentation.
* Fix equals/hashCode.
* Move caffeine out of extension.
* Remove `JsonTypeName` from the class itself
* Fix bad docs
* Fix distribution pom
* Fix unused import
* Make caffeine default
* Address code comments
* Add more description around the jre version in the readme
* Add suggested comments
* Move emitters from io.druid.server.initialization to the dedicated io.druid.server.emitter package; Update emitter library to 0.6.0; Add support for ParametrizedUriEmitter; Support hierarical properties in JsonConfigurator (was needed for ParametrizedUriEmitter)
* Log created RequestLoggers
* Fix forbidden API
* Test fix
* More Http and Parametrized Http Emitter docs
* Switch to debug level
* fixes HttpServerInventoryView to call server/segment callbacks correctly and Unit Tests for the class
* fix checkstyle and forbidden-api errors
* HttpServerInventoryView to finish start() only after server inventory is initialized
* fix compilation errors
* address review comments
* add exponential backoff instead of fixed 5 secs on successive failures
* update test to exercise server fail scenarios
* use AtomicInteger for requestNum and increment only once
