Dear all,
One of the Flink jobs gave below exception and failed. Several attempts to restart the job resulted in the same exception and the job failed each time. The job started successfully only after changing the job name. Flink Version: 1.11.2 Exception 2021-03-24 20:13:09,288 INFO org.apache.kafka.clients.producer.KafkaProducer [] - [Producer clientId=producer-2] Closing the Kafka producer with timeoutMillis = 0 ms. 2021-03-24 20:13:09,288 INFO org.apache.kafka.clients.producer.KafkaProducer [] - [Producer clientId=producer-2] Proceeding to force close the producer since pending requests could not be completed within timeout 0 ms. 2021-03-24 20:13:09,304 WARN org.apache.flink.runtime.taskmanager.Task [] - Flat Map -> async wait operator -> Process -> Sink: Unnamed (1/1) (8905142514cb25adbd42980680562d31) switched from RUNNING to FAILED. java.io.IOException: No such file or directory at java.io.UnixFileSystem.createFileExclusively(Native Method) ~[?:1.8.0_252] at java.io.File.createNewFile(File.java:1012) ~[?:1.8.0_252] at org.apache.flink.runtime.io.network.api.serialization.SpanningWrapper.createSpillingChannel(SpanningWrapper.java:291) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.io.network.api.serialization.SpanningWrapper.updateLength(SpanningWrapper.java:178) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.io.network.api.serialization.SpanningWrapper.transferFrom(SpanningWrapper.java:111) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.io.network.api.serialization.SpillingAdaptiveSpanningRecordDeserializer.readNonSpanningRecord(SpillingAdaptiveSpanningRecordDeserializer.java:110) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.io.network.api.serialization.SpillingAdaptiveSpanningRecordDeserializer.getNextRecord(SpillingAdaptiveSpanningRecordDeserializer.java:85) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.streaming.runtime.io.StreamTaskNetworkInput.emitNext(StreamTaskNetworkInput.java:146) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.streaming.runtime.io.StreamOneInputProcessor.processInput(StreamOneInputProcessor.java:67) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.streaming.runtime.tasks.StreamTask.processInput(StreamTask.java:351) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.streaming.runtime.tasks.mailbox.MailboxProcessor.runMailboxStep(MailboxProcessor.java:191) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.streaming.runtime.tasks.mailbox.MailboxProcessor.runMailboxLoop(MailboxProcessor.java:181) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.streaming.runtime.tasks.StreamTask.runMailboxLoop(StreamTask.java:566) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:536) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:721) [flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.taskmanager.Task.run(Task.java:546) [flink-dist_2.12-1.11.2.jar:1.11.2] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_252] 2021-03-24 20:13:09,305 INFO org.apache.flink.runtime.taskmanager.Task [] - Freeing task resources for Flat Map -> async wait operator -> Process -> Sink: Unnamed (1/1) (8905142514cb25adbd42980680562d31). 2021-03-24 20:13:09,311 INFO org.apache.flink.runtime.taskexecutor.TaskExecutor [] - Un-registering task and sending final execution state FAILED to JobManager for task Flat Map -> async wait operator -> Process -> Sink: Unnamed (1/1) 8905142514cb25adbd42980680562d31. File: https://github.com/apache/flink/blob/release-1.11.2/flink-runtime/src/main/java/org/apache/flink/runtime/io/network/api/serialization/SpanningWrapper.java Related Jira ID: https://issues.apache.org/jira/browse/FLINK-18811 Similar exception mentioned in FLINK-18811 which has a fix in 1.12.0. Though in our case, we didn't notice any disk failure. Is there any other reason(s) for the above mentioned IOException? While we are planning to upgrade to the latest Flink version, are there any other workaround(s) instead of deploying the job again with a different job name? Kind regards, Vinaya |

Hi Vinaya, SpillingAdaptiveSpanningRecordDeserializer tries to create a directory in the temp directory, which you can configure by setting io.tmp.dirs. By default, it's set to System.getProperty("java.io.tmpdir"), which seems to be invalid in your case. (Note that the directory has to exist on the task managers) Best, Arvid On Thu, Mar 25, 2021 at 7:27 AM VINAYA KUMAR BENDI <[hidden email]> wrote:

Hi Arvid,
Thank you for the suggestion. Indeed, the specified setting (io.tmp.dirs) was commented out in the Flink configuration (flink-conf.yaml). # io.tmp.dirs: /tmp However, "java.io.tmpdir" was configured to "/tmp" as can be verified from below command. $ java -XshowSettings VM settings: Max. Heap Size (Estimated): 6.89G Ergonomics Machine Class: server Using VM: OpenJDK 64-Bit Server VM Property settings: awt.toolkit = sun.awt.X11.XToolkit ... java.io.tmpdir = /tmp ... From task manager log: org.apache.flink.shaded.zookeeper3.org.apache.zookeeper.ZooKeeper [] - Client environment:java.io.tmpdir=/tmp Also, the read and write access to /tmp is working. $ touch /tmp/somefile $ ls -l /tmp/somefile -rw-rw-r--. 1 centos centos 0 Mar 26 06:28 /tmp/somefile Kind regards, Vinaya -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/ |

Hi Vinaya, java.io.tmpdir is already the fallback and I'm not aware of another level of fallback. Ensuring java.io.tmpdir is valid is also relevant for some third-party libraries that rely on it (e.g. FileSystem that cache local files). It's good practice to set that appropriately.
