Hi Ankush,

I'm facing a situation, where the spark submit is not getting killed after the process is complete.Due to this the other processes are stuck and its not able to continue the process.
Below is my spark-conf:
spark.driver.memory 16g
spark.executor.memory 4G
spark.executor.cores 2
It has 1-master and 1-node, master acts as worker also. 32GB RAM, 4cores each machine
Can u suggest me why this error happens and what would be the best spark-conf for this architecture
