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. Regards, Raja.

I am not able to trace logs also. Also, FYI, our FLINK cluster(4nodes) is setup on our Hadoop YARN cluster. Thanks a lot. Regards, Raja.
