The kSpillWriteBufferSize is set to 4M by typo. correct it to 1M. The value control the buffer size when spill write data to disk. it also control the read buffer size when spill data is fetch back. The memory will be allocated as offheap memory. So if there are to many spill files, the memory will exceed offheap size and trigger the OOM issue by operator::getOutput. the spill files number is impacted by MaxSpillFileSize and MaxSpillRunRows, both are the smaller the more spill files. -- This is an automated message from the Apache Git Service.
