Aaron Kimball updated MAPREDUCE-1235:
-------------------------------------

    Attachment: MAPREDUCE-1235.patch

Attaching patch to fix this issue. MySQL supports TIMESTAMP values of '0000-00-00 00:00:00'
which is out-of-range for java.sql.Timestamp. MySQL allows various behaviors for handling
this; the default used to be to convert this value to null; since MySQL 5 it now throws IOException
when such a timestamp is retrieved.

Sqoop now sets the default behavior to be convert these values to 'null', since this is a
reasonable data conversion given the imprecision available. Users can override this default
by passing the {{zeroDateTimeBehavior=exception}} parameter in the connect string.
