> Project: Hive
> Issue Type: Improvement
> Components: UDF
> Affects Versions: 0.10.0, 0.11.0
> Reporter: Xuefu Zhang

> Currently UDF context_ngrams() output top-K ngrams in the order of descending
> frequency. When there are ties, i.e., phrases with same ngram value, the
> order is indeterministic. Tie breaker is needed to break the ties, so that
> the output is deterministic.
