@rxin Originally this pr computed endpoints for equi-width (distinct
values) or equi-height histograms (percentiles), then @srinathshankar gave a
comment
[here](https://github.com/apache/spark/pull/15637#pullrequestreview-6319075)
and I think it was reasonable, so I adopted it. Now this pr computes distinct
values and their counts for building equi-width histograms, and when ndv >
threshold, it returns an empty result. I just updated description of the
corresponding Jira.
