> 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.
