Danny Lee commented on SPARK-33001:
-----------------------------------
[~xorz57] - I followed the code back to 1305 in this file
[https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/util/Utils.scala]
but unfortunately even if I set my system to "isTesting" like in line 1930 the
debug output for computePageSize() only shows the number 4096. I think this is
in early stages of testing, but I dont think it was affecting my code at all
and my job was failing for a different reason (most likely memory related).
The warning just happened to show up before my exception, but I believe its
unrelated.
