Lefty Leverenz commented on HIVE-16996:
---------------------------------------
Doc note: This adds *hive.stats.ndv.algo* to HiveConf.java, so it needs to be
documented in the Statistics section of Configuration Properties.
* [Configuration Properties -- Statistics |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Statistics]
Added a TODOC3.0 label.
> Add HLL as an alternative to FM sketch to compute stats
