Hi Debraj, thanks for reaching out to the Flink community. Without knowing the details on how you've set up the Single-Node YARN cluster, I would still guess that it is a configuration issue on the YARN side. Flink does not know about a .flink folder. Hence, there is no configuration to set this folder.
