MySQLIntegrityConstraintViolationException but not keys duplicated
Hi all,

All our MySQL tables have  composite primary keys (8 fields) and when we use sqoop for insert into them(from hive), we are getting this exception:
java.io.IOException: Can't export data, please check task tracker logs
        at org.apache.sqoop.mapreduce.TextExportMapper.map(TextExportMapper.java:112)

Caused by: java.io.IOException: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '33-2013-02-13 23:00:00-Brasil-Play-None-None-None-None-  Filmes  for key 'PRIMARY

There are no duplicated keys in our Hive tables however. Is there any constraint related to the number of fields that can belong to a PK?
