> Sqoop will fail with OutOfMemory on large tables using mysql

> Key: MAPREDUCE-685
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-685
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: contrib/sqoop
> Reporter: Aaron Kimball
> Assignee: Aaron Kimball
> Attachments: MAPREDUCE-685.patch, MAPREDUCE-685.patch.2
>
>
> The default MySQL JDBC client behavior is to buffer the entire ResultSet in
> the client before allowing the user to use the ResultSet object. On large
> SELECTs, this can cause OutOfMemory exceptions, even when the client intends
> to close the ResultSet after reading only a few rows. The MySQL ConnManager
> should configure its connection to use row-at-a-time delivery of results to
> the client.
