---------------------------------
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.
