Subject [jira] [Created] (SQOOP-1617) MySQL fetch-size behavior changed with SQOOP-1400
Date Thu, 23 Oct 2014 08:05:33 GMT
Jürgen Thomann created SQOOP-1617:

             Summary: MySQL fetch-size behavior changed with SQOOP-1400
                 Key: SQOOP-1617
                 URL: https://issues.apache.org/jira/browse/SQOOP-1617
             Project: Sqoop
          Issue Type: Bug
          Components: connectors/mysql
    Affects Versions: 1.4.6
         Environment: CDH 5.2
sqoop 1.4.5 (seems to include SQOOP-1400)
mysql connector version 5.1.33
            Reporter: Jürgen Thomann
            Priority: Minor

SQOOP-1400 changed the default behavior for the connector to load everything in memory. The
only working way to get the old streaming back is to use --fetch-size -2147483648 (Integer.MIN_VALUE)

It would be nice if that could be changed and/or documented that mysql does not support a
fetch size and does only support row-by-row or loading everything in memory
