Description
This bug was introduced in https://github.com/apache/tez/commit/a47e8fcbea5eeab5a7cf812271d329524cc02dba?diff=split
when combiner != null, the change in this commit passes kvIter with next() having already been called. This ends up (silently) dropping the first record in the partition.
Will submit PR and attach patch. jeagles, not sure if this is the way you want to fix or not but it does fix my tests.
