Thanks Matthias for replying. Yes there was some yarn configuration issue on my side which I mentioned in my last email.
I am starting on flink. So just for my understanding in few links (posted below) it is reported that flink needs to create a .flink directory in the users home folder. Even though I am not using HDFS with yarn (in single-node deployment) but I am also observing the same. Is there a way I can configure the location where flink stores the jar and configuration file as mentioned in the below link? https://wints.github.io/flink-web//faq.html#the-yarn-session-crashes-with-a-hdfs-permission-exception-during-startup >From the above link *"Flink creates a .flink/ directory in the users home directory where it stores the Flink jar and configuration file."* Same mentioned here <https://docs.cloudera.com/csa/1.2.0/installation/topics/csa-hdfs-home-install.html> . <https://wints.github.io/flink-web//faq.html#the-yarn-session-crashes-with-a-hdfs-permission-exception-during-startup> On Fri, Feb 26, 2021 at 9:45 PM Matthias Pohl <matth...@ververica.com> wrote: > Hi Debraj, > thanks for reaching out to the Flink community.
