ColumnFamilyOutputFormat will only write out one column
Alex Burkoff also reported this nearly two months ago, but nobody ever
has anyone any ideas?
should it be possible to write multiple columns out?
This is very easy to reproduce. Use the contrib/wordcount example, with
OUTPUT_REDUCER=cassandra and in WordCount.java add at line 132
> results.add(getMutation(key, sum));
> + results.add(getMutation(new Text("doubled"), sum*2));
Only the last mutation for any key seems to be written.
