Lefty Leverenz commented on HIVE-1653:
--------------------------------------

This adds *hive.stats.reliable* to HiveConf.java and hive-default.xml.template (see patch
in Facebook reviews, since it isn't attached here:  https://reviews.facebook.net/D4119).

> This is a follow-up for https://issues.apache.org/jira/browse/HIVE-1361.
> If one of the mappers/reducers cannot publish stats, it may lead to wrong aggregated
stats.
> There should be a way to avoid this - at the least, a configuration variable which fails
the 
> task if stats cannot be published
