L. C. Hsieh commented on SPARK-26570:
-------------------------------------
I think the collected number of filestatus can be more than 70K, considering
bulkListLeafFiles lists leaf files under paths recursively? Yes, a heap dump
can be more helpful.

> The *bulkListLeafFiles* will collect all filestatus in memory for every query
> which may cause the oom of driver. I use the spark 2.3.2 meeting with the
> problem. Maybe the latest one also exists the problem.
