Aaron Kimball updated MAPREDUCE-685: ------------------------------------ Status: Patch Available (was: Open) > 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 > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
