Chen Li commented on ASTERIXDB-1751:
------------------------------------
Does it mean the main reason is that a partition file is not closed properly?
The fix is to call close() properly?
> Some of spilled partition files are not deleted properly after the optimized
> hybrid hash join finishes.

> Some of spilled partition files are not deleted. The condition is:
> 1) A partition is spilled to the disk during the build phase.
> 2) That partition doesn't receive any tuple after that spill.
> Then, the file is not explicitly closed during "closeAllSpilledPartition"
> call. So, during the probe phase, even though the file will be open again
> with "delete on close call". When closing the file, since a file handle is
> still holding the file, it is not deleted properly.
