Subject Making a RowCounterIterator
Date Fri, 15 Jul 2016 18:24:30 GMT
I'm trying to create a RowCounterIterator that counts all the rows and
returns only one key-value with the counter inside. The problem is that I
can't get it work. The Scala code is available in the gist
<> together
with some pseudo-code of a test. The problem is that if I add an entry to
my table, this iterator will return 0 instead of 1 and apparently the
reason is that super.hasTop() is always false. I've tried without the
iterator and the scanner returns 1 elements. Any idea of what I'm doing
wrong here? Is WrappingIterator the right class to extend for this kind of
