Dears, I would like to re-open a case for a potential bug (current status is resolved but it sounds not) :
*https://issues.apache.org/jira/browse/SPARK-12261 <https://issues.apache.org/jira/browse/SPARK-12261>* I believe there is something wrong about the memory management under windows It has no sense to work with files smaller than a few Mo... Do not hesitate to ask me questions if you try to help and reproduce the bug, Best Christopher Bourez 06 17 17 50 60
