Eric Lin updated SQOOP-3039:
----------------------------
Attachment: SQOOP-3039.patch
java.sql.Time does not support time in "hh:mm:ss.fffffffff" format, only
"hh:mm:ss".
So I have created a customized Time class to support nano seconds and switched
to use this class instead.

> To re-produce:
> Set up MySQL database with following schema:

> CREATE TABLE `test` (
> `a` time(2) DEFAULT NULL
> ) ENGINE=InnoDB DEFAULT CHARSET=latin1
> {code}
> Store the following data in HDFS:
> {code}
> 16:56:53.0999
> 16:56:54.1
> 16:56:53.0000
> 16:56:54.1230
> {code}
> run Sqoop export command to copy data from HDFS into MySQL:
> {code}
> qoop export --connect jdbc:mysql://<mysql-host>/test --username root
> --password password --table test -m 1 --driver com.mysql.jdbc.Driver
> --export-dir /tmp/test
> {code}
> Command will fail with the following error:

> Looks like Sqoop uses java.sql.Time.valueOf function to convert
> "16:56:53.0999" to Time object, however, this function only accepts Time in
> "hh:mm:ss" format:
