Re: MySQLIntegrityConstraintViolationException but not keys duplicated
ZORAIDA HIDALGO SANCHEZ 2013-07-04, 02:07
Hi Jarcec,

Thanks for your response. I am afraid that the --verbose option does not
give us more information:

13/07/04 04:04:16 ERROR mapreduce.AsyncSqlOutputFormat: Got exception in
update thread:
com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException:
 Duplicate entry '63-2013-02-27

The reason why I am suggestion that PK is being truncated is because as
you can see here: '63-2013-02-27
00:00:00-Brasil-Play-SVoD-ODG-Unknown-Unknown-Unkn', Unkn is not finished
and that can be the reason of why are we getting this
MySQLIntegrityConstraintViolationException. I have search on MySQL but I
do not see any hint.

Thanks again,

Zoraida.-
