Lefty Leverenz commented on HIVE-7155:
--------------------------------------
Doc note: *templeton.mapper.memory.mb* is documented in the WebHCat
Configuration wiki, at the end of the table of configuration variables.
(Better late than never.) I took the liberty of changing "Templeton" to
"WebHCat" in the description -- should have thought of that before the commit.

> Reporter: shanyu zhao

> Submit a Hive query on a large table via WebHCat results in failure because
> the WebHCat controller job is killed by Yarn since it exceeds the memory
> limit (set by mapreduce.map.memory.mb, defaults to 1GB):
> {code}
> INSERT OVERWRITE TABLE Temp_InjusticeEvents_2014_03_01_00_00 SELECT * from
> Stage_InjusticeEvents where LogTimestamp > '2014-03-01 00:00:00' and
> LogTimestamp <= '2014-03-01 01:00:00';
> {code}
> We could increase mapreduce.map.memory.mb to solve this problem, but this way
> we are changing this setting system wise.
> We need to provide a WebHCat configuration to overwrite
> mapreduce.map.memory.mb when submitting the controller job.
