Jonathan Ellis updated CASSANDRA-1922:
--------------------------------------
Attachment: 1922.txt
Patch includes test to reproduce the problem and a (one-line) fix in
CompactionManager. Also includes comments on AbstractCompactionIterator as to
what each method is supposed to include, to make it easier to avoid this
mistake in the future.
