Thanks a lot Lasse.
So, the recommendation is to update the property “blob.storage.directory”, to some maintained path, other than “/tmp”, so the default cleanup will be eliminated ?
Also can you pls confirm if this is a hdfs path or a Local unix path ?
Please acknowledge if I have understood is correctly?
Thanks a lot again.

My Flink application which reads from Kafka and writes to HDFS is failing repeatedly with below exception:

Can someone please help me on, what could be the root cause of this issue? I am not able to trace logs also.
Also, FYI, our FLINK cluster(4nodes) is setup on our Hadoop YARN cluster.
Thanks a lot.
