Chris Douglas updated MAPREDUCE-1290:
-------------------------------------
Status: Patch Available (was: Open)
Rerunning through Hudson
> DBOutputFormat does not support rewriteBatchedStatements when using MySQL
> jdbc drivers

> Key: MAPREDUCE-1290

>
> The DBOutputFormat adds a semi-colon to the end of the INSERT statement that
> it uses to save fields to the database. Semicolons are typically used in
> command line programs but are not needed when using the JDBC API. In this
> case, the stray semi-colon breaks rewriteBatchedStatement support. See:
> http://forums.mysql.com/read.php?39,271526,271526#msg-271526 for an example.
> In my use case, rewriteBatchedStatement is very useful because it increases
> the speed of inserts and reduces memory consumption.
