> Hbase Scan may be using more memory than is mentioned in the query profile
> --------------------------------------------------------------------------
>
> Key: IMPALA-806
> URL: https://issues.apache.org/jira/browse/IMPALA-806
> Project: IMPALA
> Issue Type: Bug
> Components: Perf Investigation
> Affects Versions: Impala 1.2.3
> Reporter: Udai Kiran Potluri
> Assignee: Alan Choi
> Priority: Minor
> Labels: resource-management
>
> Possible memory usage miscalculation when scanning Hbase data. When Cgroup is
> set to 10GB and mem_limit set to 8GB, the Impala Daemon was killed because
> the service reached 10GB memory usage. However the peak memory usage per node
> only showed few hundred KB usage.
> Hbase scan may be using more memory than what is shown in the Query Profile.
