The BlobStoreService's lifecycle is exclusively managed by the HighAvailabilityServices. This means that the BlobStore's content is only cleaned up if the HighAvailabilityService's HA data is cleaned up. Having this single point of control, makes it easier to decide when to discard HA data (e.g. in case of a successful job execution) and when to retain the data (e.g. for recovery). Close and cleanup all data of BlobStore in HighAvailabilityServices Use HighAvailabilityServices to create BlobStore Introduce BlobStoreService interface to hide close and closeAndCleanupAllData methods This closes #3864. --- .../org/apache/flink/hdfstests/HDFSTest.java | 14 ++- .../clusterframework/MesosTaskManager.scala | 6 +- .../runtime/webmonitor/WebRuntimeMonitor.java | 26 +++++- .../handlers/TaskManagerLogHandler.java | 11 ++- .../webmonitor/WebRuntimeMonitorITCase.java | 14 ++- .../handlers/TaskManagerLogHandlerTest.java | 11 ++- .../apache/flink/runtime/blob/BlobCache.java | 80 ++++------------ .../apache/flink/runtime/blob/BlobServer.java | 38 ++++---- .../flink/runtime/blob/BlobService.java | 8 +- .../apache/flink/runtime/blob/BlobStore.java | 26 +----- .../flink/runtime/blob/BlobStoreService.java | 32 +++++++ .../apache/flink/runtime/blob/BlobUtils.java | 44 ++++++++- .../apache/flink/runtime/blob/BlobView.java | 49 ++++++++++ .../runtime/blob/FileSystemBlobStore.java | 11 ++- .../flink/runtime/blob/VoidBlobStore.java | 8 +- .../flink/runtime/client/JobClient.java | 13 ++- .../runtime/client/JobListeningContext.java | 6 +- .../clusterframework/BootstrapTools.java | 8 +- .../librarycache/BlobLibraryCacheManager.java | 2 +- .../HighAvailabilityServicesUtils.java | 12 ++- .../nonha/AbstractNonHaServices.java | 5 +- .../zookeeper/ZooKeeperHaServices.java | 93 +++++++++---------- .../runtime/jobmaster/JobManagerServices.java | 2 +- .../runtime/taskexecutor/TaskExecutor.java | 5 +- .../runtime/webmonitor/WebMonitorUtils.java | 21 +++-- .../flink/runtime/jobmanager/JobManager.scala | 21 +++-- .../minicluster/FlinkMiniCluster.scala | 8 +- .../minicluster/LocalFlinkMiniCluster.scala | 8 +- .../runtime/taskmanager/TaskManager.scala | 36 +++++-- .../runtime/blob/BlobCacheRetriesTest.java | 79 ++++++++-------- .../runtime/blob/BlobCacheSuccessTest.java | 56 +++++------ .../flink/runtime/blob/BlobClientSslTest.java | 52 +++++------ .../flink/runtime/blob/BlobClientTest.java | 16 +--- .../runtime/blob/BlobRecoveryITCase.java | 21 +++-- .../runtime/blob/BlobServerDeleteTest.java | 21 +++-- .../flink/runtime/blob/BlobServerGetTest.java | 41 +++----- .../flink/runtime/blob/BlobServerPutTest.java | 89 +++++------------- .../runtime/blob/BlobServerRangeTest.java | 10 +- .../blob/TestingFailingBlobServer.java | 4 +- .../BlobLibraryCacheManagerTest.java | 33 +++---- .../BlobLibraryCacheRecoveryITCase.java | 21 +++-- .../zookeeper/ZooKeeperRegistryTest.java | 7 +- .../jobmanager/JobManagerHARecoveryTest.java | 9 +- .../JobManagerLeaderElectionTest.java | 3 +- .../ZooKeeperLeaderRetrievalTest.java | 13 ++- .../metrics/TaskManagerMetricsTest.java | 2 +- ...kManagerComponentsStartupShutdownTest.java | 5 +- .../TaskManagerRegistrationTest.java | 5 +- .../src/test/resources/log4j-test.properties | 2 +- .../JobManagerRegistrationTest.scala | 3 +- .../testingUtils/TestingTaskManager.scala | 40 ++++---- ...erHAProcessFailureBatchRecoveryITCase.java | 1 + .../flink/yarn/TestingYarnTaskManager.scala | 25 ++--- .../YarnHighAvailabilityServices.java | 30 +++++- .../apache/flink/yarn/YarnTaskManager.scala | 6 +- 55 files changed, 667 insertions(+), 545 deletions(-) create mode 100644 flink-runtime/src/main/java/org/apache/flink/runtime/blob/BlobStoreService.java create mode 100644 flink-runtime/src/main/java/org/apache/flink/runtime/blob/BlobView.java diff --git a/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/HDFSTest.java b/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/HDFSTest.java index 8a3f66263e2240..08158639b1759e 100644 --- a/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/HDFSTest.java +++ b/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/HDFSTest.java @@ -31,6 +31,8 @@ import org.apache.flink.core.fs.Path;

Only after all ZooKeeperStateHandleStores have released their lock, the ZNode is allowed to be deleted. THe locking mechanism is implemented via ephemeral child nodes of the respective ZooKeeper node. Whenever a ZooKeeperStateHandleStore wants to lock a ZNode, thus, protecting it from being deleted, it creates an ephemeral child node. The node's name is unique to the ZooKeeperStateHandleStore instance. The delete operations will then only delete the node if it does not have any children associated. In order to guard against oprhaned lock nodes, they are created as ephemeral nodes. This means that they will be deleted by ZooKeeper once the connection of the ZooKeeper client which created the node timed out. --- .../store/ZooKeeperMesosWorkerStore.java | 8 +- .../ZooKeeperCompletedCheckpointStore.java | 150 +++--- .../ZooKeeperSubmittedJobGraphStore.java | 50 +- .../zookeeper/ZooKeeperStateHandleStore.java | 419 ++++++++++++---- .../CompletedCheckpointStoreTest.java | 9 + ...oKeeperCompletedCheckpointStoreITCase.java | 133 +++-- ...ZooKeeperCompletedCheckpointStoreTest.java | 11 +- ...ava => ZooKeeperStateHandleStoreTest.java} | 465 ++++++++++++------ 8 files changed, 854 insertions(+), 391 deletions(-) rename flink-runtime/src/test/java/org/apache/flink/runtime/zookeeper/{ZooKeeperStateHandleStoreITCase.java => ZooKeeperStateHandleStoreTest.java} (55%) diff --git a/flink-mesos/src/main/java/org/apache/flink/mesos/runtime/clusterframework/store/ZooKeeperMesosWorkerStore.java b/flink-mesos/src/main/java/org/apache/flink/mesos/runtime/clusterframework/store/ZooKeeperMesosWorkerStore.java index 42abd4cdd82d79..663ce566d6d756 100644 --- a/flink-mesos/src/main/java/org/apache/flink/mesos/runtime/clusterframework/store/ZooKeeperMesosWorkerStore.java +++ b/flink-mesos/src/main/java/org/apache/flink/mesos/runtime/clusterframework/store/ZooKeeperMesosWorkerStore.java @@ -88,7 +88,7 @@ public void stop(boolean cleanup) throws Exception { totalTaskCountInZooKeeper.close(); if(cleanup) { - workersInZooKeeper.removeAndDiscardAllState(); + workersInZooKeeper.releaseAndTryRemoveAll(); } isRunning = false; @@ -169,7 +169,7 @@ public List recoverWorkers() throws Exception { synchronized (startStopLock) { verifyIsRunning(); - List, String>> handles = workersInZooKeeper.getAll(); + List, String>> handles = workersInZooKeeper.getAllAndLock(); if(handles.size() != 0) { List workers = new ArrayList<>(handles.size()); @@ -199,7 +199,7 @@ public void putWorker(MesosWorkerStore.Worker worker) throws Exception { int currentVersion = workersInZooKeeper.exists(path); if (currentVersion == -1) { try { - workersInZooKeeper.add(path, worker); + workersInZooKeeper.addAndLock(path, worker); LOG.debug("Added {} in ZooKeeper.", worker); } catch (KeeperException.NodeExistsException ex) { throw new ConcurrentModificationException("ZooKeeper unexpectedly modified", ex); @@ -227,7 +227,7 @@ public boolean removeWorker(Protos.TaskID taskID) throws Exception { return false; } - workersInZooKeeper.removeAndDiscardState(path); + workersInZooKeeper.releaseAndTryRemove(path); LOG.debug("Removed worker {} from ZooKeeper.", taskID); return true; } diff --git a/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/ZooKeeperCompletedCheckpointStore.java b/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/ZooKeeperCompletedCheckpointStore.java index 95cfb0f977ff0b..084d93e7ca24dc 100644 --- a/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/ZooKeeperCompletedCheckpointStore.java +++ b/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/ZooKeeperCompletedCheckpointStore.java @@ -19,9 +19,6 @@ package org.apache.flink.runtime.checkpoint; import org.apache.curator.framework.CuratorFramework; -import org.apache.curator.framework.api.BackgroundCallback; -import org.apache.curator.framework.api.CuratorEvent; -import org.apache.curator.framework.api.CuratorEventType; import org.apache.curator.utils.ZKPaths; import org.apache.flink.api.java.tuple.Tuple2; import org.apache.flink.runtime.jobgraph.JobStatus; @@ -34,12 +31,12 @@ import org.slf4j.Logger; import org.slf4j.LoggerFactory; +import javax.annotation.Nullable; import java.util.ArrayDeque; import java.util.ArrayList; import java.util.ConcurrentModificationException; import java.util.Iterator; import java.util.List; -import java.util.concurrent.Callable; import java.util.concurrent.Executor; import static org.apache.flink.util.Preconditions.checkArgument; @@ -155,7 +152,7 @@ public void recover() throws Exception { List, String>> initialCheckpoints; while (true) { try { - initialCheckpoints = checkpointsInZooKeeper.getAllSortedByName(); + initialCheckpoints = checkpointsInZooKeeper.getAllSortedByNameAndLock(); break; } catch (ConcurrentModificationException e) { @@ -178,7 +175,7 @@ public void recover() throws Exception { "checkpoint store.", e); // remove the checkpoint with broken state handle - removeBrokenStateHandle(checkpointStateHandle); + removeBrokenStateHandle(checkpointStateHandle.f1, checkpointStateHandle.f0); } if (completedCheckpoint != null) { @@ -201,7 +198,7 @@ public void addCheckpoint(final CompletedCheckpoint checkpoint) throws Exception final RetrievableStateHandle stateHandle; // First add the new one.

In order to find out the address to which to bind, the ClusterClient tries to connect to the JobManager. In order to find out the JobManager's address it is important to use the HighAvailabilityServices instead of retrieving the address information from the configuration, because otherwise it conflicts with HA mode.
