Subject [jira] [Commented] (ASTERIXDB-1751) Some of spilled partition files are not deleted properly after the optimized hybrid hash join finishes.

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. 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.
