Hi. We have migrated to Flink 1.10 and face out of memory exception and hopeful can someone point us in the right direction.
We have a job that use broadcast state, and we sometimes get out memory when it creates a savepoint. See stacktrack below. We have assigned 2.2 GB/task manager and configured taskmanager.memory.process.size : 2200m In Flink 1.9 our container was terminated because OOM, so 1.10 do a better job, but it still not working and the task manager is leaking mem for each OOM and finial kill by Mesos Any idea what we can do to figure out what settings we need to change? Thanks in advance Lasse Nedergaard WARN o.a.flink.runtime.state.filesystem.FsCheckpointStreamFactory - Could not close the state stream for s3://flinkstate/dcos-prod/checkpoints/fc9318cc236d09f0bfd994f138896d6c/chk-3509/cf0714dc-ad7c-4946-b44c-96d4a131a4fa. java.io.IOException: Cannot allocate memory at java.io.FileOutputStream.writeBytes(Native Method) at java.io.FileOutputStream.write(FileOutputStream.java:326) at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:82) at java.io.BufferedOutputStream.flush(BufferedOutputStream.java:140) at java.io.FilterOutputStream.flush(FilterOutputStream.java:140) at java.io.FilterOutputStream.close(FilterOutputStream.java:158) at com.facebook.presto.hive.s3.PrestoS3FileSystem$PrestoS3OutputStream.close(PrestoS3FileSystem.java:995) at org.apache.hadoop.fs.FSDataOutputStream$PositionCache.close(FSDataOutputStream.java:72) at org.apache.hadoop.fs.FSDataOutputStream.close(FSDataOutputStream.java:101) at org.apache.flink.fs.s3presto.common.HadoopDataOutputStream.close(HadoopDataOutputStream.java:52) at org.apache.flink.core.fs.ClosingFSDataOutputStream.close(ClosingFSDataOutputStream.java:64) at org.apache.flink.runtime.state.filesystem.FsCheckpointStreamFactory$FsCheckpointStateOutputStream.close(FsCheckpointStreamFactory.java:277) at org.apache.flink.util.IOUtils.closeQuietly(IOUtils.java:263) at org.apache.flink.util.IOUtils.closeAllQuietly(IOUtils.java:250) at org.apache.flink.util.AbstractCloseableRegistry.close(AbstractCloseableRegistry.java:122) at org.apache.flink.runtime.state.AsyncSnapshotCallable.closeSnapshotIO(AsyncSnapshotCallable.java:167) at org.apache.flink.runtime.state.AsyncSnapshotCallable.call(AsyncSnapshotCallable.java:83) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at org.apache.flink.runtime.concurrent.FutureUtils.runIfNotDoneAndGet(FutureUtils.java:458) at org.apache.flink.streaming.api.operators.OperatorSnapshotFinalizer.<init>(OperatorSnapshotFinalizer.java:53) at org.apache.flink.streaming.runtime.tasks.StreamTask$AsyncCheckpointRunnable.run(StreamTask.java:1143) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) INFO org.apache.flink.runtime.checkpoint.CheckpointCoordinator -
