Hello Vahid,
am testing one of our Kafka Stream Apps with the 2.2.1-rc, after few minutes, I see this WARN: 2019-05-09 13:14:37,025 WARN [test-app-id-dc27624a-8e02- 4031-963b-7596a8a77097-StreamThread-1] internals.ProcessorStateManager ( ProcessorStateManager.java:349) - task [0_0] Failed to write offset checkpoint file to [/tmp/kafka-stream-app/test-app-id/0_0/.checkpoint] java.io.FileNotFoundException: /tmp/kafka-stream-app/test-app-id/0_0/.checkpoint.tmp (No such file or directory) at java.io.FileOutputStream.open0(Native Method) ~[?:1.8.0_191] at java.io.FileOutputStream.open(FileOutputStream.java:270) ~[?:1.8.0_191] at java.io.FileOutputStream.<init>(FileOutputStream.java:213) ~[?:1.8.0_191] at java.io.FileOutputStream.<init>(FileOutputStream.java:162) ~[?:1.8.0_191] at org.apache.kafka.streams.state.internals.OffsetCheckpoint.write( OffsetCheckpoint.java:79) ~[kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.ProcessorStateManager.checkpoint( ProcessorStateManager.java:347) [kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.StreamTask.commit( StreamTask.java:476) [kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.StreamTask.suspend( StreamTask.java:598) [kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.StreamTask.close( StreamTask.java:724) [kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.AssignedTasks.close( AssignedTasks.java:337) [kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.TaskManager.shutdown( TaskManager.java:267) [kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.StreamThread.completeShutdown( StreamThread.java:1208) [kafka-streams-2.2.1.jar:?] at org.apache.kafka.streams.processor.internals.StreamThread.run( StreamThread.java:785) [kafka-streams-2.2.1.jar:?] Checking the system, in fact, the folder does not exist, but, others were created: # ls /tmp/kafka-stream-app/test-app-id/ # 1_0 1_1 1_2 After restarting the App, the same WARN shows-up but in this case, the folders were created but not the .checkpoint.tmp file: # ls /tmp/kafka-stream-app/test-app-id/ # 0_0 0_1 0_2 1_0 1_1 1_2 Am just reporting this because I found it strange/suspicious.
