SocketTimeout exception when running a display command on spark dataframe

[Manjusha]

I am using runtime 9.1LTS

I have a R notebook that reads a csv into a R dataframe and does some transformations and finally is converted to spark dataframe using the createDataFrame function.

after that when I call the display function on this spark dataframe, I get the following error

org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 0.0 failed 4 times, most recent failure: Lost task 0.3 in stage 0.0 (TID 3) (10.139.64.4 executor 0): java.net.SocketTimeoutException: Accept timed out

In the spark UI, in stderr, I can see this message

BufferedStream Thread: Error in file(filename, "r", encoding = encoding)

But when I run this same code in the uat environment that has the same runtime(9.1LTS) this is not happening.

Also, till yesterday we were using 8.2 runtime and the error was not happening.

Any help is much appreciated
