Sylvain Lebresne updated CASSANDRA-3260:
----------------------------------------
Attachment: 3260_v2.patch
Hum, I don't think that works because both OneToOne and TrivialOneToOne
constructors do sources.get(0), so that should stay a == 1.
The initial idea was to use the manyToOne that works fine will an empty list of
sources, but attaching an alternative v2 that adds a simple EmptyIterator for
the empty case.
> MergeIterator assertion on sources != empty can be thrown

> MergeIterator.get assert that it don't get an empty list of sources. This
> seems to at least not be the case in the unit test for some of tests (this
> don't make any test fail however, but there is a few stack trace thrown). I
> think it's pretty unnatural to "fail" on an empty list of sources and would
> force every caller to first take the empty case into account, so I propose to
> just remove that assertion.
