Deprecated Interfaces

Interface and Description
org.apache.flink.runtime.state.internal.InternalFoldingState will be removed in a future version

Deprecated Classes

Class and Description
org.apache.flink.runtime.state.heap.HeapFoldingState will be removed in a future version
org.apache.flink.runtime.rest.handler.job.metrics.JobVertexMetricsHandler This class is subsumed by SubtaskMetricsHandler and is only kept for backwards-compatibility.
org.apache.flink.runtime.rest.handler.legacy.metrics.JobVertexMetricsHandler This class is subsumed by SubtaskMetricsHandler and is only kept for backwards-compatibility.
org.apache.flink.runtime.checkpoint.TaskState Internal class for savepoint backwards compatibility. Don't use for other purposes.
org.apache.flink.runtime.rest.messages.YarnCancelJobTerminationHeaders This should be removed once we can send arbitrary REST calls via the Yarn proxy.
org.apache.flink.runtime.rest.messages.YarnStopJobTerminationHeaders This should be removed once we can send arbitrary REST calls via the Yarn proxy.

Deprecated Methods

Method and Description
org.apache.flink.runtime.history.FsJobArchivist.archiveJob(Path, AccessExecutionGraph) only kept for legacy reasons
org.apache.flink.runtime.executiongraph.ExecutionGraphBuilder.buildGraph(ExecutionGraph, JobGraph, Configuration, ScheduledExecutorService, Executor, SlotProvider, ClassLoader, CheckpointRecoveryFactory, Time, RestartStrategy, MetricGroup, int, BlobWriter, Time, Logger)
org.apache.flink.runtime.checkpoint.savepoint.SavepointV2.convertToOperatorStateSavepointV2(Map<JobVertexID, ExecutionJobVertex>, Savepoint) Only kept for backwards-compatibility with versions < 1.3. Will be removed in the future.
org.apache.flink.runtime.state.AbstractKeyedStateBackend.createFoldingState(TypeSerializer<N>, FoldingStateDescriptor<T, ACC>) will be removed in a future version
org.apache.flink.runtime.state.filesystem.FsStateBackend.getBasePath() Deprecated in favor of FsStateBackend.getCheckpointPath().
org.apache.flink.runtime.rest.handler.legacy.metrics.MetricStore.getJobManager() Use semantically equivalent MetricStore.getJobManagerMetricStore().
org.apache.flink.runtime.highavailability.HighAvailabilityServices.getJobManagerLeaderRetriever(JobID) This method should only be used by the legacy code where the JobManager acts as the master.
org.apache.flink.runtime.io.network.buffer.Buffer.getMemorySegment()
org.apache.flink.runtime.io.network.buffer.Buffer.getMemorySegmentOffset()
org.apache.flink.runtime.state.DefaultOperatorStateBackend.getOperatorState(ListStateDescriptor<S>) This was deprecated as part of a refinement to the function names. Please use DefaultOperatorStateBackend.getListState(ListStateDescriptor) instead.
org.apache.flink.runtime.state.DefaultOperatorStateBackend.getSerializableListState(String) Using Java serialization for persisting state is not encouraged. Please use DefaultOperatorStateBackend.getListState(ListStateDescriptor) instead.
org.apache.flink.runtime.checkpoint.savepoint.Savepoint.getTaskStates() Only kept for backwards-compatibility with versionS < 1.3. Will be removed in the future.
org.apache.flink.runtime.jobmanager.scheduler.CoLocationConstraint.isAssignedAndAlive() Should only be called by legacy code (if using Scheduler)
org.apache.flink.runtime.operators.hash.InMemoryPartition.overwriteRecordAt(long, T) Don't use this, overwrites record and causes inconsistency or data loss for overwriting everything but records of the exact same size
org.apache.flink.runtime.jobmaster.LogicalSlot.releaseSlot() Added because extended the actual releaseSlot method with cause parameter.
org.apache.flink.runtime.net.SSLUtils.setSSLVerAndCipherSuites(SSLEngine, Configuration) Use SSLUtils.createClientSSLEngineFactory(Configuration) or SSLUtils.createServerSSLEngineFactory(Configuration).
org.apache.flink.runtime.rest.handler.legacy.backpressure.BackPressureStatsTrackerImpl.triggerStackTraceSample(ExecutionJobVertex) BackPressureStatsTrackerImpl.getOperatorBackPressureStats(ExecutionJobVertex) will trigger stack trace sampling automatically.

Deprecated Constructors

Constructor and Description
org.apache.flink.runtime.checkpoint.savepoint.SavepointV2(long, Collection<TaskState>) Only kept for backwards-compatibility with versions < 1.3. Will be removed in the future.
org.apache.flink.runtime.leaderretrieval.StandaloneLeaderRetrievalService(String) Use StandaloneLeaderRetrievalService.StandaloneLeaderRetrievalService(String, UUID) instead
