* Set is_available to false by default for published segment
* Address comments
Fix the is_published value for segments not in metadata store
* Remove unused import
* Use non-null sharSpec for a segment in test
* Fix checkstyle
* Modify comment
* Broker: Await initialization before finishing startup.
In particular, hold off on announcing the service and starting the
HTTP server until the server view and SQL metadata cache are finished
initializing. This closes a window of time where a Broker could return
partial results shortly after startup.
As part of this, some simplification of server-lifecycle service
announcements. This helps ensure that the two different kinds of
announcements we do (legacy and new-style) stay in sync.
* Remove unused imports.
* Fix NPE in ServerRunnable.
* SQL: Add support for queries with project-after-semijoin.
These didn't work before, since the top Project rel wasn't getting
merged into the DruidSemiJoin rel. This patch allows that to happen.
* Null handling
* Null handling
* Null handling
* make logs that are only useful for debugging be at debug level so log volume is much more chill
* info level messages for total merge buffer allocated/free
* more chill compaction logs
* FilteredRequestLogger: Fix start/stop, invalid delegate behavior.
Fixes two bugs:
1) FilteredRequestLogger did not start/stop the delegate.
2) FilteredRequestLogger would ignore an invalid delegate type, and
instead silently substitute the "noop" logger. This was due to a larger
problem with RequestLoggerProvider setup in general; the fix here is
to remove "defaultImpl" from the RequestLoggerProvider interface, and
instead have JsonConfigurator be responsible for creating the
default implementations. It is stricter about things than the old system
was, and is only willing to make a noop logger if it doesn't see any
request logger configs. Otherwise, it'll raise a provision error.
* Remove unneeded annotations.
* FileUtils: Sync directory entry too on writeAtomically.
See the fsync(2) man page for why this is important:
https://linux.die.net/man/2/fsync
This also plumbs CompressionUtils's "zip" function through
writeAtomically, so the code for handling atomic local filesystem
writes is all done in the same place.
* Remove unused import.
* Avoid FileOutputStream.
* Allow non-atomic writes to overwrite.
* Add some comments. And no need to flush an unbuffered stream.
* Double-checked locking bug is fixed.
* @Nullable is removed since there is no need to use along with @MonotonicNonNull.
* Static import is removed.
* Lazy initialization is implemented.
* Local variables used instead of volatile ones.
* Local variables used instead of volatile ones.
* Fix travis timeout in BufferHashGrouperTest
* adjust buffer size
* adjust bufferSize and loadFactor
* increase memory
* add debug code
* cat error
* after script
* print logs
* print per 2 min
* use direct mem
* clean up
The documentation for Bound filter's lowerStrict/upperStrict is incorrect. It is not consistent with the examples provided and actual behaviour of the bound filter. Correct this.
* autosize processing buffers based on direct memory sizing
* remove oops, more test
* max 1gb autosize buffers, test, start of docs
* fix oops
* revert accidental change
* print buffer size in exception
* change the things
* remove AbstractResourceFilter.isApplicable because it is not, add tests for OverlordResource.doShutdown and OverlordResource.shutdownTasksForDatasource
* cleanup
`sessionToken`, `accessKey` and `secretKey` must be updated atomically.
Another race is possible between the file updater and the Druid process reading the file. It could be enforced only with mandatory file locking, but file locking is advisory by default in Linux.
Not putting this to 0.13 milestone because the found bugs are not critical (one is a harmless DI config duplicate, and another is in a benchmark.
Change in `DumpSegment` is just an indentation change.
