Thomas Jungblut commented on HAMA-723:
--------------------------------------
Thanks!
bq.mergeFiles() function of Merger.java, when merging finished, there is no
call to "dos.close()", data lost may happen. Also, in sortAndSpill function of
SortedFile.java, os.close() missing.
It is not missing, this is the new try/catch with resources. You can read more
about that here:
http://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html
Streams are auto closed when reaching the end of the try block.
> Implement sorting in spilling queue.
