shahid commented on SPARK-29765:
--------------------------------
I still not sure about the root cause, as I am not able to reproduce with small
data. From the number I can see that it is something related to cleaning up the
store, when the number of tasks exceeds the threshold. If you can still
reproduce with the same data even after increasing the threshold, then it might
be due to some other issue.
