d619f51 [FLINK-4788] [streaming api] Fix state backend classloading from configuration 10 October 2016, 12:40:52 UTC
7267562 [FLINK-4777] catch IOException in ContinuousFileMonitoringFunction FileSystem.listStatus(path) may throw an IOException when it lists files and then retrieves their file status. This is quite common, e.g. editors which create temporary files and move them. The ContinuousFileMonitoringFunction can only apply a file path filter afterwards. The solution is to defer file checks until no exception is caught anymore. This closes #2610. 10 October 2016, 08:46:41 UTC
bab59df [FLINK-4329] Fix Streaming File Source Timestamps/Watermarks Handling This closes #2593. 05 October 2016, 15:52:26 UTC

a83dbae [hotfix] [kafka] Committed offset value set in KafkaTopicPartitionState should also be incremented by 1. The broken behaviour was introduced in the last hotfix commit eece0dd0. 05 October 2016, 10:50:14 UTC
a31a22e [FLINK-4732] remove maven junction plugin On Windows, the plugin downloads and executes code from the author's web site. The downloaded file is not signed in the same way as Maven artifacts from Maven central which have to be signed with the developer's key. This could be a potential target for attackers. This closes #2586 04 October 2016, 13:49:09 UTC

90d7759 [FLINK-4702] [kafka connector] Commit offsets to Kafka asynchronously and don't block on polls Letting the Kafka commit block on polls means that 'notifyCheckpointComplete()' may take very long. This is mostly relevant for low-throughput Kafka topics. 30 September 2016, 10:39:53 UTC
caa0fbb [FLINK-4672] [taskmanager] Do not decorate Actor Kill messages 26 September 2016, 09:25:01 UTC
62c666f [FLINK-4485] close and remove user class loader after job completion Keeping the user class loader around after job completion may lead to excessive temp space usage because all user jars are kept until the class loader is garbage collected. Tests showed that garbage collection can be delayed for a long time after the class loader is not referenced anymore. Note that for the class loader to not be referenced anymore, its job has to be removed from the archive. The fastest way to minimize temp space usage is to close and remove the URLClassloader after job completion. This requires us to keep a serializable copy of all data which needs the user class loader after job completion, e.g. to display data on the web interface. 24 September 2016, 12:21:07 UTC

5184d0b [FLINK-4314] [tests] Fix test instability in JobManagerHAJobGraphRecoveryITCase The test was relying on the JobManager shutting down before the TaskManager, which is not necessarily the case. If the TaskManager shuts down before the JobManager, the JobGraph could reach the final state FAILED, in which case all HA state is removed. To circumvent this, we add a restart strategy. 05 August 2016, 09:53:25 UTC

2495184 [FLINK-4296] Fixes failure reporting of consumer task scheduling when producer has already finished This PR changes the failure behaviour such that the consumer task is failed instead of the producer task. The latter is problematic, since a finsihed producer task will simply swallow scheduling exception originating from scheduling the consumer task. This closes #2321. 02 August 2016, 18:24:36 UTC

c71a0c7 [FLINK-4307] [streaming API] Restore ListState behavior for user-facing ListStates 02 August 2016, 18:24:35 UTC
ac7028e Revert "[FLINK-4154] [core] Correction of murmur hash breaks backwards compatibility" This reverts commit 81cf2296683a473db4061dd3bed0aeb249e05058. We had an incorrent implementation of Murmur hash in Flink 1.0. This was fixed in 641a0d4 for Flink 1.1. Then we thought that we need to revert this in order to ensure backwards compatability between Flink 1.0 and 1.1 savepoints (81cf22). Turns out, savepoint backwards compatability is broken for other reasons, too. Therefore, we revert 81cf22 here, ending up with a correct implementation of Murmur hash again. 02 August 2016, 18:24:35 UTC

cd232e6 [FLINK-4261][tools] retry in case of failed snapshot deployment Unfortunately, we can't deploy snapshots atomically using the Nexus repository. The staged process which leads to an atomic deployment is only designed to work for releases. Best we can do is to retry deploying artifacts in case of failures. - introduce retry in case of failure of snapshot deployment - simplify deployment script This closes #2296 26 July 2016, 14:46:47 UTC
2648bc1 [FLINK-4152] Allow re-registration of TMs at resource manager - Add YarnFlinkResourceManager test to reaccept task manager registrations from a re-elected job manager - Remove unnecessary sync logic between JobManager and ResourceManager - Avoid duplicate reigstration attempts in case of a refused registration - Add test case to check that not an excessive amount of RegisterTaskManager messages are sent - Remove containersLaunched from YarnFlinkResourceManager and instead not clearing registeredWorkers when JobManager loses leadership - Let YarnFlinkResourceManagerTest extend TestLogger - Harden YarnFlinkResourceManager.getContainersFromPreviousAttempts - Add FatalErrorOccurred message handler to FlinkResourceManager; Increase timeout for YarnFlinkResourceManagerTest; Add additional constructor to TestingYarnFlinkResourceManager for tests - Rename registeredWorkers field into startedWorkers Additionally, the RegisterResource message is renamed into NotifyResourceStarted which tells the RM that a resource has been started. This reflects the current semantics of the startedWorkers map in the resource manager. - Fix concurrency issues in TestingLeaderRetrievalService This closes #2257 26 July 2016, 14:39:22 UTC

f0ac261 [FLINK-4067] [runtime] Add savepoint headers Savepoints were previously persisted without any meta data using default Java serialization of `CompletedCheckpoint`. This commit introduces a savepoint interface with version-specific serializers and stores savepoints with meta data. Savepoints expose a version number and a Collection<TaskState> for savepoint restore. Currently, there is only one savepoint version: SavepointV0 (Flink 1.1): This is the current savepoint version, which holds a reference to the Checkpoint task state collection, but is serialized with a custom serializater not relying on default Java serialization. Therefore, it should not happen again that we need to stick to certain classes in future Flink versions. The savepoints are stored in `FsSavepointStore` with the following format: MagicNumber SavepointVersion Savepoint - MagicNumber => int - SavepointVersion => int (returned by Savepoint#getVersion()) - Savepoint => bytes (serialized via version-specific SavepointSerializer) The header is minimal (magic number, version). All savepoint-specific meta data can be moved to the savepoint itself. This is also were we would have to add new meta data in future versions, allowing us to differentiate between different savepoint versions when we change the serialization stack. All savepoint related classes have been moved from checkpoint to a new sub package `checkpoint.savepoint`. This closes #2194. 26 July 2016, 09:30:43 UTC

0360fb9 [hotfix] [gelly] Reduce maximum number of generator blocks The default maximum akka transfer size is 10 MB. This commit reduces the number of generator blocks from 2^20 to 2^15 which removes the limit on graph size. The original limit of one millions blocks was intended to future-proof scalability.

3213016 [FLINK-4150] [runtime] Don't clean up BlobStore on BlobServer shut down The `BlobServer` acts as a local cache for uploaded BLOBs. The life-cycle of each BLOB is bound to the life-cycle of the `BlobServer`. If the BlobServer shuts down (on JobManager shut down), all local files will be removed. With HA, BLOBs are persisted to another file system (e.g. HDFS) via the `BlobStore` in order to have BLOBs available after a JobManager failure (or shut down). These BLOBs are only allowed to be removed when the job that requires them enters a globally terminal state (`FINISHED`, `CANCELLED`, `FAILED`). This commit removes the `BlobStore` clean up call from the `BlobServer` shutdown. The `BlobStore` files will only be cleaned up via the `BlobLibraryCacheManager`'s' clean up task (periodically or on BlobLibraryCacheManager shutdown). This means that there is a chance that BLOBs will linger around after the job has terminated, if the job manager fails before the clean up. This closes #2256. 25 July 2016, 13:20:26 UTC
2818ee0 [hotfix] Prevent CheckpointCommitter from failing job Prevents the CheckpointCommitter from failing a job, if either commitCheckpoint() or isCheckpointCommitter() failed. Instead, we will try again on the next notify(). This closes #2287 25 July 2016, 12:52:55 UTC

54f02ec [FLINK-4201] [runtime] Forward suspend to checkpoint coordinator Suspended jobs were leading to shutdown of the checkpoint coordinator and hence removal of checkpoint state. For standalone recovery mode this is OK as no state can be recovered anyways (unchanged in this PR). For HA though this lead to removal of checkpoint state, which we actually want to keep for recovery. We have the following behaviour now: -----------+------------+------------------- | Standalone | High Availability -----------+------------+------------------- SUSPENDED | Discard | Keep -----------+------------+------------------- FINISHED/ | Discard | Discard FAILED/ | | CANCELED | | -----------+------------+------------------- This closes #2276. 22 July 2016, 12:26:40 UTC
