> numeric columns in Hive tables and partitions. This task involves a)
> implementing a UDAF to compute equi-height histograms on numeric columns, b)
> persisting the histogram to the metastore along with other column statistics
> , c) enhancing the thrift api to retrieve the histogram along with the other
> statistics and d) extending the grammar of ANALYZE to allow the user to
> request histograms and specify the number of bins.
