Hi Nimmi,

Can you send us the spark parameters with overhead. assuming you are
running with yarn

Example

[4] - 864GB

--num-executors 32

--executor-memory 21G

--executor-cores 4
--conf spark.yarn.executor.memoryOverhead=3000

 The parameter spark.yarn.executor.memoryOverhead is explained as below:

 spark.yarn.executor.memoryOverhead = executorMemory * 0.10, with minimum
of 384

 The amount of off-heap memory (in megabytes) to be allocated per executor.
This is memory that accounts for things like VM overheads, interned
strings, other native overheads, etc. This tends to grow with the executor
size (typically
6-10%).
