Ning Zhang commented on HIVE-2127:
----------------------------------
@Namit, what does the new configuration variable do? Do you mean to define a
variable to disable retry? If so set hive.stats.retries.max = 0 will do.
> Improve stats gathering reliability by retries on failures

> Stats publishing and aggregation only try once and if there is any exception
> it will fail and return. If many mappers/reducers updating stats at the same
> time, it is very common to get lock timeout. We should make stats more
> reliable by retry when there is an SQLException.
