---------------------------------

             Summary: WebHCat controller job exceeds container memory limit
                 Key: HIVE-7155
                 URL: https://issues.apache.org/jira/browse/HIVE-7155
             Project: Hive
          Issue Type: Bug
          Components: WebHCat
    Affects Versions: 0.13.0
            Reporter: shanyu zhao
            Assignee: 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.
